Connecting Factory Nav to Aftermarket Unit (CAMBUS, ANDROID UNIT)

[yyz_bobby]

Hi guys

I purchased a Joying single din unit, for the most part its really good, easy to use and has lots of great features.

However I have lost

1) steering wheel controls - for which I hope an additional harness from Connect2 will resolve

2) any control over my factory Nav (which I eventually want to remove) BUT would like to still have the computer info such as range, mpg....mostly mpg feed to my android unit.

So the first pic there are behind the android unit 3 particular wires I have questions on that I hope someone can answer or assist with.

1) There is a Green CAN OUT, some reason this is connected already to the white KEY wire
2) There is a grey CAN IN which can just about be spotted under the purple IR wire


Second pic is the factory Sat Nav partially removed, is there any techical clever way for the wiring for that loom in the picture to be easily cut off from factory nav without errors?
Are there wires in that loom which relate to the ones in the first pic that by some means can read the usual info from the car.

NOTE: Within the joying android unit there is a setup menu for CANBUS where it asks you to pick car etc....

Thanks
Bobby
