Another successful upgrade complete.  Ordered one last week from ebay. Looked a bit beat up but for $130 delivered I figured I would roll the dice.  Turned up on Friday. Wires were cut but that ended up being a good thing.  I managed to splice my own USB cable by connecting the end that was left in the unit from the wire cutting with using a standard USB extension which I trimmed the Male end off.  Bit of trial and error with the USB.  Initially I had the USB data wires backwards.  For any one attempting this, get the power pins right which is an easy check with a multi meter.  Data cables should not kill your device (based on the iPhone not getting fried when I tested). I owe a credit to someone here who posted up some USB wiring stuff.   I have a reverse camera on the way. I will try to remember to get some pics of that when the camera turns up.
Can you give me the link from where you ordered the unit because I can't find GD03.
I got it from a wrecker advertising on ebay.  Just did a search for 'gd-03' and did a buy it now.

Following up from my earlier post

My earlier post

I have now managed to get the reverse camera installed.  I didn't grab pictures.  I was really short on time and the better half had been bundled inside on a wet day with the kids so I was 'on a short fuse'.  It took a lot more than I thought to get the camera installed and wired up so sharing a few lessons.

some pointers for people that want to do the same
this is the camera I purchased
Cheap generic ebay reverse camera

1) Take the back of the rear seat off on the drivers side - it will save you time in the long run
2) Removing the material lining in the rear quarter was made easier after I did step # 1)
3) There is no access (that I could find) to the bumper from inside the car.  I ran the wires for the camera past the indicator wiring (also on the drivers side).  I did this by cutting a slit in the boot that provides a seal for the wires.  Granted it's no longer 100% waterproof but its probably about 98% which I was OK with.
4) Camera doesn't work with a flat battery - don't flatten your battery by listening to the new Radio while you do this bit. 
5) I ran the sensor/power wire all the way to the bulb in the hatch I suspect there is an easier option but I'm not sure where the wiring harness for the reverse lights runs inside the cabin.  Looks like it may run across the roof??.   
6) Power from the reverse lights hooked to the sensor as well as the power for the camera works fine (no delay in image displaying).
7) In the wiring for the GD-01 harness there are no pins in the harness for the reverse camera in pin 14 and 15 of harness A.  Hopefully if you got a radio with cut wires you can extract a couple and insert them in the right holes, this is what I did. Make sure the terminals are seated all the way in.  Pin 14 Ground should connect to the outside of the RCA connector for the camera.  15 connects to the inside pin of the RCA connector.  Pin 9 Adapter A (the one you have to cut to make the GD-03 radio work) should connect to the reverse sensor wire (to tell the radio to switch to reverse camera mode). I had an old female RCA connector I wired up to make this connection easier.
 

The camera unit purchased did not support the stock light fitting for the number plate illumination light. The light fits OK in the hole but the locking pins don't enable it to lock the light in place.  I wrapped it with electrical tape which will hold it in place.  I also notices the globe was blown so I will need to revisit this bit.

RESULT: it works. 

OPEN ISSUES: There are two sets of  red/yellow/green lines on the screen when in reverse mode.  One set from the headunit and one set from the camera.  I didn't see any wires to cut on the camera to disable fro there and can't see and way to disable on the head unit.  Any ideas on how to do this on the head unit???

GUIDE UPDATE - USB CABLE

I did the upgrade from a GD-01 earlier this year and was able to get complete functionality without the USB port assembly and cable. Here are my results in case anyone is in a similar position.

WHAT YOU WILL NEED

If you do not have the GD-03 USB assembly you can buy a pre-made cable like this one


Has anyone used these cables before? I got a price from PC Parts and Cables and it works out about $15 incl shipping to Australia.

I bought this cable and installed it using my original AUX/USB assembly. I removed the cover and the PCB, then the USB socket clicked into place.

Apple Carplay works great, now to upgrade the firmware.
