Best Privacy Policy and Terms of Service in an app

I found one of the best examples of a privacy policy and terms of service in an app in a long time!

I downloaded and installed a Heart Rate Variability (HRV) app on my phone this morning and whilst the app won't work for me (more on this below) I was very impressed with their implementation of the terms of service and privacy policy.  During the onboarding it was very clear what Terms of Service were as it was in simple plain English and not legalese.  It was short and concise in a dot point format and clearly made sure that it was clear that they were going to use your data but it was still owned by you.

It was short enough I actually skimmed / read the Terms before pressing the Continue.  Surprisingly there was no easy option to not continue.  I suppose for me the phone back button would have been the option.  


The next step was the Privacy Policy which was almost as easy to review as the Terms of Service.  Again the summary was clear as to what the privacy policy was about.


I wish all app developers who are collecting data for use would simplify their terms and privacy policies.  I'm sure there were more detailed versions of both somewhere on the Elite HRV app site and in app although I didn't attempt to read any more.  

I can't understand the ridiculousness of expecting users to 'read' and agree to the terms when there are pages and pages and pages of information.  Why bother?  I wonder what percentage would have even gone past the first "page" of the terms of things like when you first load up an iPhone?  I know they have the option of emailing the terms to yourself but you have already agreed at that point even if you do end up reading the 100+ (app) pages of terms! 

Often called "clickwrap" there is the implication that you have read it if you click the button (in this case the "Continue" link.  

We, as everyday users, have to rely on the good will of the organisations that build the app.  What about the Face App (the one that creates an "older" version of people) which seems to have terms indicating they can store and use the data - even after you have long deleted the app -- and the developers are based in Russia?!  Eeek!  I got wrapped up in that too.  

If everyone had to create simple English terms which were agreed to it would make the app world a better place!

One of my gripes about the user experience of the Elite HRV app which is where the above Terms and Privacy Policy are from is the 'compatibility" which indicated that as a Samsung Note 8 user it would be compatible (assuming that was going to be using the camera on my phone to measure my heart rate... ) and yet when I was trying to get a reading wanted to connect to a Bluetooth... something!  (assume a heart rate monitor).  Their site needs to be clearer that Android devices maybe compatible with ANT+ and other heart rate monitors but you still need the heart rate monitor to work!

Bathing in Vitamin C and Water Dechlorination in an Apartment

In the past I have had a home which had a whole of house filter.  To filter out all the chlorine in the home and even the fluoride for drinking.  Since I've moved to an apartment things have to be a bit different as the water that comes into the apartment for hot water is already hot.  Which means any "whole" of apartment filter needs to be able to cope with hot water too.  It's not that there isn't such a thing just that it was too hard to get the right plumber in for the job who knew what they were doing.

So I decided to just get an over the sink kitchen filter for drinking water (and cooking and cleaning fishtanks and watering plants) and for my shower I just got a shower filter.  And I worked out that I could buy special vitamin c tablets to dechlorinate my bath water. 

I've been using the dechorination tablets for over a year (you get about 20 tablets per tube and I got 5 tubes) when my mum was telling me about how she's going to start having baths again (since she moved into a new place).  So I gave her a tube to try.  She LOVED it.  She raved how wonderfully it felt and how it meant her skin was no longer flaking and dry.  That's a huge wrap from her!  I had given her a new brand of tablets which I had bought from Amazon.  Unfortunately getting them here in Australia was super expensive (as Amazon forces you to get it from Australian Amazon).  So something that was A$18.99 became A$70!  I ended up getting a set from US Amazon and sending it to a shipment fulfilment service.  I paid a lot for the shipping but I think I still ended up slightly ahead (maybe $4...)

So this post is very much just sharing that I think Vitamin C tablets for a bath are great and does stop the flaky skin and the feeling of dry skin. 

Now I'm wondering if just buying vitamin C powder will have the same effect as I think that will be a lot cheaper than buying tablets.

I'll post back after I give it a go :)

Transitioning to Apartment Living

I've now moved to Hurstville into a 1 bedroom apartment... with 2 dogs ... from a house for a year.  And LOVE it.

In this post I talk about some of the things I love about apartment living.  I also cover some of the gotchas and what I don't like about it.

1.  Security

I love the secure feeling of living in this particular apartment block.  I know it's not universal with all apartments but one of the things I was seeking was a feeling of security (or rather a lack of not feeling safe.)  I live on a high floor which helps too.  If I had all the same features but was on the first or ground floor I don't think it would be the same at all.
My apartment block has a swipe card/fob access for the lobby door and then a further swipe is required to get to any floor on the lift.  My apartment door then has a normal lock although I've seen other people install an additional lock I don't feel the need for this.  My floor only has a handful of apartments so well seem to recognise each other.

2.  Garbage Chute

I love, love, love having a garbage chute.  What is this magical thing?  Well it's a handle box thing which you pull open, throw your garbage (in a garbage or plastic bag please!!) close the box thing and voila... garbage is no longer in your life.  Ever.  (Don't throw out anything you want because goodness knows where it goes and I don't think you will ever see it again!)  It's very cathartic.  I believe there are lots of people who are watching the Marie Kondo Netflix series... and any decluttering person will tell you that you should not let your stuff own you.
The garbage chute is inside a garbage room which has space for me to put my recycling.  When I first moved in I had a lot of IKEA boxes.  And I mean a LOT.  The room was chockers full with my recycling and the next day I opened the door (probably to put more IKEA boxes into it!) and it was *poof* gone.  I mean magically.  It was an amazing feeling.  And our apartment block has cleaners who keep the room nice and clean and tidy.  It never smells funny or is left dirty.

3.  Storage Cage and Parking Spot

In my last house, we had a double ++ garage.  It was huge and we also had roof space and under house space where we could store stuff.  I thought I would miss having a garage where my car was kept safe and away from the other 'stranger' cars.  But the car space system works fine.  It's good to have enough space on either side of the car to get in and out and good to know that all there is space for is the car.  Once I get down to the car space I'm in the car and away!  (but I do have to go up 4 ramps and two security doors before I can get out but I do have a remote opener so it's not too bad).

The storage cage is also good.  It's good that it's far away in a sense and I do have enough storage in my apartment for most things so only the large things that I don't have space for or need for on a day to day basis goes down there.  Things like suitcases and not yet used potting mix or dog food or if anyone is going to Costco and buying toilet paper!  Mainly I put my suitcase and half worked on projects (I'm looking at you Big Mirror Project!) and my trolleys for big items.  Oh and that giant rug I still hang onto cos I love it but my apartment is too small for.  (I really should give it away... )

I lock the storage cage with a lock with chain - similar to a bicycle or motorcycle lock.  People are able to see into my cage and I don't have anything special in there so I don't expect there to be any theft.  It's good as it's not very dusty down there nor is it damp and it is well lit so all in all I think it's an improvement to most sheds or garages.

4.  Low maintenance (although high costs)

Living in a small apartment is great!  Dusting and vacuuming is minimal (well compared to a house!) and no lawns need mowing.  I only have one bathroom to clean and I clean as I go (as in I don't have a dedicated cleaning schedule).  My balcony is undercover so a sweep and mop is good to keep it clean even though I have two dogs.

The strata for the building is expensive especially since the only 'special' things is the two lifts our building has.  But cleaning and maintenance isn't free so each of us have to pay our share.  Having said that I believe maintenance for a house (time spent mowing, mowing, cleaning gutters etc) can add up over a year so for the < $5000 I pay per annum I think it's an OK trade.

5.  Mod cons (modern conveniences)

I live in a fairly new apartment so have a lot of the modern conveniences.  I installed an air conditioning unit when I moved in but probably only used it 10 times in the last year either for heating or cooling.  But it's good to know it's there.  The apartment comes with appliances such as the dishwasher, microwave and dryer (although I've had to replace the dryer).  The place also comes with an intercom for security and access.

It's hard to think of anything that this apartment needs.  Maybe one of those 3 in 1 things in the bathroom for winter.

I did replace all the halogen downlights with LEDs but as they were easily replaced.

6. Convenience

There's little not to love about my apartment!  The convenience most of all.  The ability to lock up and go is great and the location makes it super handy for me to get public transport around Sydney and also in Hurstville I get access to a Westfields as well as lots of restaurants and banking services.

7. Views and breeze

How can I forget one of the selling points of this apartment?  The view!  The view from this apartment is phenomenal!  And with it comes the breeze.  I'm fortunate to have an east facing apartment.  I originally looked at getting a north facing apartment but I actually think this is better!  Views of the ocean, airport and city... sunrises that are so magical.  Moon rises too!  And all whilst being protected on the north and south by neigbour's properties!  So I get a cooling breeze without the gale force winds.

Things which are a little annoying:

Lack of bathroom window for air - the compact size means both my laundry and bathroom are "internal" and have no windows to the outside.  Actually in my apartment I have NO windows!  But I have two massive stacker doors that lead out to the balcony.

Noise from upstairs - the noise from neighbours can be annoying if they are stomping around in the middle of the night but I think that my neighbours above must be away most of the year as I only occasionally get a few nights of noise.  And then silence for the rest of the year.  So I'm happy when they are all away!

Waiting for a lift - if you are in rush this could be annoying.  With two lifts servicing the building there are some times where you need to be patient and wait for the lift.  Unfortunately you can't rush these things.  If desperate there is always the stairs (although I have yet to work out how to get into the stairwell from downstairs).

Keys! - don't forget them! - every time I go out I double check for keys.  Unless I'm holding the keys in my hand when I'm about to leave my apartment I don't walk away.  The door self locks so I'm always worried one day I'll lock myself out.

That's it.  I can't think of any other things that don't work for me.  I'm sure there are small things but overall I just love it!  Yay to apartment living!

Startups - I can multitask right?

One of my co-founders of CrowdQuests / HackSauce has rightly pointed out that my last post was saying I am only focusing on one Startup.  Well I was.  But then we did GovHack 2018... and started up a new startup CrowdQuests which is something I find we at Transport for NSW need and I'm sure other data hungry organisations also need.  We've often talked about getting data more accurate and crowdsourced to keep costs low.  So now there is such a company and app that does that.  CrowdQuests :)

So CrowdQuests is the product and HackSauce is the organisation that has the four founders attached to it.  I say attached as we have it currently as a partnership with the 4 companies that each of the founders is a sole director of as partners.  I know confusing, right?  But it works for us and we are likely to incorporate HackSauce to make things a bit easier when submitting tenders and quotes and proposals.

More about CrowdQuests and what we are doing in a different post when I have a bit more time... but I also started a new blog which may or may not become a 'thing'... because I've been following a ketogenic diet for the last couple of months.  The blog is Keto4Asians.  It's a resource for me to share my keto stuff and knowledge.  And will obviously have a bent towards Asian related foods.  But I just blog about whatever.  I've also set up a matching Twitter and Instagram account.  Let's see what happens with it but it's meant to be a low effort (mainly because of my interest) activity and also helps me keep motivated in following the keto-esque diet.  I am doing what they call "lazy keto" as I am not tracking much except estimating in keeping my net carbs under 20 grams.

Why I'm ditching all my startups

I wrote this in 2017 but never published it.  Not for any real reason but just because it wasn't finished and I forgot about it.  In August 2018 I'm resurrecting it and publishing it.  Just in case it helps someone. 


A few weeks ago we shut down 99interns 😢 after a few years in the market and good market recognition.  I shut down oddswop a couple of years ago (well kinda shut down.  I still need to deregister the company and finalise all the tax stuff).  But I still had New Home Review which was setup relatively recently and BadgerMe which was a couple of years old.  But even those are being shut down.  The BadgerMe back end was closed out last week and New Home Review, I've advised Ciaran and other people working on things that I'm shutting it down as well.  Because...

I'm going all in on one startup.  Yes ONE.  And it's not even mine.  Well it is mine but I won't be the Founder.  I'll be the co-founder.

It's definitely been a super busy time for me but also a time where due to the pressure my ideas and values have been made clearer.  I've been super busy with work and moreso with GovHack.  GovHack has been a gig I volunteered for and really enjoying but finding that I'm doing a lot more than I expected to.  I would easily be spending 30+ hours on it.

But it's the energy and flow from working on GovHack which has made me realise that I need the right sort of person to work with on a startup.  It's not something that I can carry alone.  All my previous startups, I've had a co-founder because I was told I should.  Or I thought it may be a good idea.  But I need to have that energy inherent in the organisation before I get there.  I can't bring it by myself.  As much as I get passionate about things I'm an empath so I tend to reflect others.  I need someone super committed and I'm happy to reflect that back.

When I met my now co-founder I was knee deep (or maybe neck deep?) in GovHack.  We found the time to talk startups and form a deep bond -- despite the fact we haven't met in real life (IRL)!  Which is kinda ironic as the new startup -- GoPlatnm.com now called HazTime so visit haztime.com -- is about IRL connections.  My co-founder was enthused but it was only after we decided to go for an accelerator that we really had to get our skates on and get something going.  So having met in May 2017 it's now early July and we've incorporated, built the site and are gearing up to apply for the accelerator all whilst being super busy everywhere.  My husband unfortunately doesn't even get to see me as I'm usually on conference calls in the evening or fixing or building or creating something for GovHack or talking strategy with my new co-founder or closing stuff down!

But here's to a new era, where I focus on the one startup.


Things which have changed since I first wrote this... I've deregistered Oddswop, my husband and I split up 😢, Platnm had a name change to HazTime, I've moved home to Hurstville, I didn't do GovHack this year so I could focus in on HazTime.

Mind Hacks and No Sugar and No Wheat

I spent about a month with minimal added sugar and wheat.  And this is what happened... I'm sure that sounds familiar.  Maybe some clickbait type headline? 

I've been wanting to reduce my wheat and sugar intake a bit and do some experimentation.  But needed a good way to force or convince myself to do it.  A mind hack. 

Mind Hacks

I love a good mind hack.  To me it's something I setup as a quasi constraint (ie a constraint totally made up by me!) that helps me towards a goal or something I want to achieve.  It's like setting artificial deadlines. 

Fasting

One of my major mind hacks is fasting.  Some of you may know that I've been doing my version of 5:2 where I fast two days a week and eat normally on the other 5 days.  Usually a 5:2 diet will allow up to 500 calories on the fasting days.  On Tuesdays and Thursdays (or days starting with "t"), I fast.  This doesn't include any coffee or tea or hot chocolates even!  And every so often I'd have a banana or yoghurt in the evening if I felt I needed it.  I've been doing this well over a year now.  And it's fairly easy.  I love the binary nature of it.  And I must have saved a tonne of money as I eat a lot less.  And a lot more time is saved as I don't need to cook and clean up those days!  But there was one stage where I would overeat ice cream and chocolate on my days where I wasn't fasting.  Not good.  The fasting is somewhat for weightloss but mainly because I'm trying to do little things that can help me not get cancer.  My mum and dad have had cancer.  So genetically I'm pretty screwed.  But there are things I can do to minimise my chances of getting cancer.  Fasting is one of them. 

Not so good things about fasting:

  • bad breath!  Maybe due to ketosis?
  • feel cold.  I think the lack of food makes my body just feel cold on the days I fast.
  • can get tremors -- I use to get this and feel really weak.  Makes sense if I'm not eating that I feel that so often I will just a small something that day to tide me over.  I'm not super strict as you can see.  But I would say I'd only break a fast once every 4 fast days.  
Good things about fasting:

  • Save money and time on the days I fast!
  • mental clarity during the days I fast
  • generally I feel my health is better (more later)
  • I realise just how little food I need!  Get a good sense of how much we generally overeat.
The big question I'm sure many people have when they hear I fast 2 days a week is if I have lost a tonne of weight.  No.  Whilst I will lose weight on those days when I fast I have pretty much stayed the same for ages.  And yes I'm still overweight.  ☹️⚖

Dry July

Since I've been feeling that I overeat on the days I can and that I have a small ice cream addiction I wanted to try and break the habit.  In May I decided that I would tell everyone that I would do "Dry July" by having no sugar and no wheat.  That would eliminate things like ice cream and chocolate but also cakes.  It's just too easy to snack on things or accept that piece of cake that is on offer.  Normally people give up alcohol in July but since I don't drink giving up sugar and wheat seemed like a good idea.  

The 'rules' were no sugar, no wheat and no sugar substitutes.  So basically no 'sweet' food.  Again I'm a non extremist so if there was a bit of sugar in a dish when eating out I would still eat it.  But I would not seek it out.  I was already such a foodtard I didn't want to make things worse for myself.  

Thank goodness my work colleagues are foodtards too and tend to understand the crazy food options we all have eliminated from our diets.  Our smallish team has an autoimmune diseased meat eater, a self induced vegan, a semi-vegan, a few dairy intolerant peeps, and a smattering of other special food needs.  

The start date was also shifted to be 2nd July as the Sunday before hand I was going to a baby shower with lots of yummy sweet things!  And I ended on 30 July.  The 31st was a Tuesday when I was meant to be fasting which should be easy but in the evening I went out with Richard after work to Newtown and had a couple of tacos (that's OK) but then wanted to try the vegan ice cream place.  Probably not worth it but at least I know I've tried it now.  (The ice cream is fine but since I'm not that lactose intolerant and Messina is down the road...) 

So all up I ended up doing no sugar, no wheat for 29 days!  Yay me!

No Sugar No Wheat -- was it worth it?

So what do I think?  I think it was a success!  I felt a lot better not eating wheat.  I'm not sure why.  I don't know if it's the wheat or the yeast that was eliminated from that side of things that made me feel better.  I know I did feel better for it.  More that I didn't feel bloated.

As for the sugar, I'm glad I did it because it broke a bit of an addiction.  How do I know?  Well I went to ALDI and didn't feel compelled to buy all the chocolate or ice cream!   During July I also had a heap of fruit.  I could tell that the lack of sweet foods was having an affect when I had to give away my pineapple to someone else because it was too sweet.  Before it was just apples that would do that to me.  But now pineapple too.  

I don't know how long this control over sugar and wheat based products will last.  But it's been a good experiment and I think I will try and incorporate it every so often if I feel that I'm getting addicted again or having excessive amounts of either sugar or wheat.  

But to the ladies out there... you should try it out.  Why do I say this?  because I had the best red week ever!  3/4 days.  Unheard of.  And not heavy but not spotting either.  I believe the culprit is sugar and not the wheat as much but I am not sure.  All I know is that I do pretty much what I do normally but with a cup of raspberry leaf tea for the first two days of my period.  But that's the only other 'different' thing I would do compared to normal.  I have been on my other supplement regime for over 2 months so that wasn't it.  Must be the sugar/wheat thing.

Magic Mirror - IKEA frame hack

Somehow I stumbled on the Magic Mirror project and of course I wanted to build it.  Forget that I was in the middle of another mirror project (still not finished) but this one is now built!

Here is the finished product (still a bit messy as I put a small console type table under the mirror): 

The console table was added... as I needed to hide the power point from my dogs who like munching on power cables if too accessible.  Before I mounted it on the wall I had it propped up on a dining room chair... 


There are plenty of resources on how to get the magic mirror tech side of things done.  The key resource is the Magic Mirror site: https://magicmirror.builders/  
I've also used Google a lot and Jayen helped me a lot too on various bits and pieces.  

The main thing that is different is the way I put the frame/mirror component together.  Here are the high level details (oxymoron?):
1. bought mirror tint from Aliexpress https://www.aliexpress.com/item/50x100cm-Window-Film-One-Way-Mirror-Silver-Insulation-Glass-Window-Film-Solar-Reflective-Home-privacy-Decoration/32658438220.html less than $5
2. bought monitor from MSY (and ended up using that as my monitor and using my old monitor for the magic mirror.  Note I didn't strip it to just a screen but just mounted the IKEA picture frame onto the monitor with a combination of sticky tape! (special mirror sticky tape!) and screws.  Samsung monitor 21.5" was $127.50 (for the new one).  
Don't get this monitor (Samsung 21.5" (LS22F355FHEX/XY) 1920x1080 5ms HDMI D-DUB VESA LED Backlight LCD monitor) for your project... you want one where the buttons and power outlet are not on the back... 
3. bought a monitor wall mount from Target with an arm.  https://www.target.com.au/p/target-full-motion-tv-wall-mount-small-to-medium/59877820  I needed to do this as otherwise there isn't enough space in behind the monitor to put cables etc.  $29
4. bought a right angle cable for power - probably around $10
5. bought a right angle cable adapter for the HDMI cable - probably around $10
6. Raspberry pi (local supplier), case (Aliexpress), PIR sensor (Aliexpress), jumper cables (Aliexpress).  Btw if you want jumper cables I now have 17 spare.  (Needed 3 for the PIR sensor connection)
7. IKEA Viserum frame https://www.ikea.com/au/en/catalog/products/30268907/ - I got the 61 x 91 cm version

I think they are the main things I needed to build the physical mirror... I may have missed bits and pieces.

The main steps was to
1. add tint to frame 'glass' 
2. put the monitor as flush as possible against the tinted 'glass'
3. add black cardboard around where the monitor screen is not... this adds to the mirror illusion
4. attach the monitor to the frame
5. mount the monitor to the wall mount
6. have the wall mount work
7. have the pi attach to the frame somehow

I also wanted to make it easy to remove/just have a normal mirror in that same spot if needed... (not as a back up plan in case I totally stuffed up of course!)

Mirror Tint application
So the key thing for me to build it initially was to cover the plastic / glass from the frame (plastic in this case!) with the tint.  This was mirror tint so it would look like a mirror on one side and could have light show through to the other side.  My tip to those who haven't tinted before is to not crinkle the tint and to use an old credit card to smooth things over.  I didn't have any special formula so just used detergent and water mixed into a spray bottle.  I didn't use distilled water.  My first few attempts looked awful.  But that's because I was using a shower squegee.  Don't do it.  Use the hard edge of a credit card.  Ideally get someone to help you so that the tint goes on in one go.  

Attach the frame to the monitor
This was relatively easy.  But I still felt like Macgyver when I found the screws with the big 'edge' and the 'edge' on the monitor!
You'll see my bodgy Macgyver skills here... I have the monitor 'sitting' on a timber brace that is attached to the frame.  Then the screws just lightly hold the screen against the frame.  I also have some mirror sticky tape on the monitor to help it stick to the frame.  




I've also just 'stuck' the Pi case using the 3M hooks for picture frames.  This makes it almost like velcro but not quite.  This worked better than expected!

You will see the monitor mount (VESA) on the back of my monitor and the 'right angle' cable and adapters I used.  

TV Mount on wall

I cheated.  I used the wall anchors for plasterboard.  As I couldn't find the battens in the wall.  (Yep add your eyerolls here!!)  



This is a side on view of the mirror -> wall.  As you can see there is a significant amount of space between the wall and the frame.  That's because I wanted to keep the monitor as whole as possible.  


I was very excited when I could finally mount it on the wall!  The project didn't take long.  Could definitely do it as a one day (a few hours?) project.  As long as you have all the bits.  The tint took ages to get to me only because the post office didn't notify me of it and was sitting there for weeks.  


So magic mirror... with newly installed PIR which is not placed optimally... who is the fairest of them all?  (most likely Pepper... or Sprocket!)

Android Head Unit for Honda Jazz

I recently bought a car!  Yay me!  It's a second hand 2008 Honda Jazz VTi Manual.


I bought the car via Carsales from a lovely lady based in Thornleigh.  And dragged Patrick from work along with me to test drive the car.  (Thanks Patrick... esp since we were stuck in traffic for such a long time!)  It's my first car in a long time as usually the car ends up in W's name and I don't actually enjoy driving so... it's really not my call as to what car to get.  But I was happy with my purchase.  It put me back $6200 (was listed at $6500).  I'm sure I could have probably gone down to $6000 but I don't like bargaining when it's for the sake of it.

The car however didn't have things like reverse sensors or Bluetooth for hands free calling.  So I could get both of those things installed or go the whole hog and get something a bit fancy.  I had been spoiled as I was driving my mum's Mazda 2 with all the bells and whistles which had a heads up display, nav, reversing camera and more.

My actual car interior
After investigation I thought to get myself an Android Head Unit.

This was installed on 23rd December 2017 by someone I found on Gumtree (yes I'd recommend him!)  I had contacted him ages ago to work out how much it would cost to install.  I had at one stage thought about installing it myself (thanks to YouTube) but was brought back to my senses by my work colleagues :)  The quote in getting a headunit installed with mic and reversing (back up) camera was $200.  And he would come to me!  (Another quote I had was for $160 but wasn't going to be available till after 5 January.)

All in the installation and the bits including head unit was less than $600.  Breakdown below with suppliers detailed.

This is what it looks like after being installed.  Looks and works great!
The stock standard stereo unit looks like this:


I like the fact it had a CD slot although I haven't listened to a CD for years.  And years.  And years. 

So to make a 2 din (ie takes up 2 standard stereo units of space) work it needed a fascia.  Then I found out that I would also need a wiring harness.  I also wanted to include a reversing camera.  So shopping was required.

The components and prices (in AUD) I ended up with are (none of the links are affiliate links or anything like that -- it just saves me from answering questions :) ):
Joying Android Head Unit (Quad Core, 2GB and Android 6.0) at $283.66 - link to the product on Aliexpress.
Reverse Camera via Aliexpress at $12.85 - link to the product on Aliexpress.
Fascia / Trim Kit for Honda Jazz GD RHD at $51.12 - link to the product on Aliexpress.
Cables/Harness Kits totalling $35.99 via eBay. I got the following items 1. Car Side Iso Connection Harness Wiring Loom, 2. Antenna Adapter To Suit Honda Jazz (Fit) Gd 2002 - 2008, 3. Head Unit Car Stereo Iso Loom Connection Harness.  I used link to the seller on eBay.
Installation was $200 - link to the service on Gumtree

Note the prices I listed above are what I paid (late 2017).  YMMV as they are often affected by exchange rates or discounts I may have received.

The reason I selected that head unit against so many others?  The reviews always influence me.  Then I wanted Android 6.0 plus to make sure I could run Android Auto (although I have since switched back to the 'standard' nav product -- more below) and I wanted to change the backlit colour...

And how did I know what cables to order?  A lot of googling and reading and watching YouTube.  But to save you some trouble I listed what I needed above.  If you happen to have and want the same setup :)  If you have a different model / make car I am sure you can just use the same terms and your make/model.

Installation

Anthony came and installed my unit after I contacted him on the 22nd... he was ready to install it at the pre-quoted price of $200 the following day!  Booyah!  He did a great job.  None of the bits I got included any additional stickers (except an NFC one which wasn't installed).  But it meant all the old stickers needed to be reused.  I didn't think it was going to be a problem as all the dials etc stay the same but I assume it was because they need to be removed and readded back... so can get damaged in the meantime.  The only thing that doesn't work quite as expected is my air cond LED no longer lights up.

Navigation

Just a note about navigation or the head unit and components themselves.  The reverse camera works a treat and is quick to bring up.  I thought I'd mention it as my neighbour who I demo'd it to was surprised at how quick it was as he had an aftermarket reverse camera installed and he thinks it takes 20 seconds to come up!  I also have the reverse green, amber, red zones.  This was demo'd to me after the installation was done so I realised how close the red zone is.  Basically I can never use the red zone!  The installer reckons the camera is a really good one.  Great $12.85 spent I say!  I chose this one over the blocky square ones that looked like they could fall off too easily. There are a lot of options on Aliexpress... so I'd suggest reading the descriptions and reviews.

As for the navigation itself that was also something the installation guy was impressed with.  It's the iGo app.  When I first drove off there were all these strange beeps that would come up and the volume levels for music vs navigation were all over the place.  And the onscreen display didn't have all the things I wanted.  But over the last few days I've tailored the settings to suit.  

The beeps were warnings.  Warnings about 40km speed zones (don't get me started on speed zone data!!  *grrrrrr*), warnings about red light cameras and speed cameras.  To stop the beeping I just need to tap the screen on the warning.  It's pretty good.  Also it warns me when I'm speeding.  And it's obvious.  It actually says "You are over the speed limit".  It's quite sensitive too.  3-4kms over and it triggers it!  

I've been using the radio (thank goodness I got the radio antenna thing!) a lot.  Bluetooth music works but seems flakey but it could be just due to some other notification that is happening on my phone.  I also transferred some music to the Head unit via a USB key.  That works OK but for now I think I'll use the radio.  It's my dose of reality.  Or "reality".  

I installed Android Auto as well as Waze.  I haven't booted up Waze yet but I did try Android Auto.  It's was my goto when I was recently in Melbourne and used it on my phone.  But you know what?  The iGo app is more feature rich.  I now have estimated arrival time, a clock, speed zone I am in as well as direction and the map etc.  And I can have the radio running in the background.  I'm not sure what it does on a normal phone or a tablet but if you are curious this is the Play store link: https://play.google.com/store/apps/details?id=com.nng.igo.primong.igoworld&hl=en

So for less than A$600 do I think it's worth it? Yep!  Approx 10% value of the car but well worth the cost to have in car nav and handsfree phone calling!  I've yet to work out if things like notifications work or anything else but I'm happy with what I've seen so far.
