Hi,

2. For what is the grey cable with the cable shoe on its end?
3. What is the handbrake cable? But iam i wright that it isn't needed if there is no DVD slot?
4. Anybody got a wiring diagram?

Hi,
1. The orange cable is for illumination.
2. The grey cable is the handbrake wire. There is not DVD slot, but you can watch video from USB cable or online.
3. The orange with black and brown with black cable are for steering wheel control which is based on analog resistance signal.
4. The pure brown wire is the Detecting wire for back a car, and the pink cable is the Remote Control for amplifier.
Hope some help.
Regards
