I haveI had originally i INA W900 Alpine headunit, (2005 Hummer H@)
I purchased a avh 4000 NEX and did not want to pay 200 plus to just switch the headunit, I attemped to do it myself
everything is now working except for the rear view camera and the sterring wheel controls
The Rearview comes up only when i select Ground on the camera settings
How do i make it work when i put in to reverse
Also The Steering Wheel Controls (which where all wired previously to my Alpine is all connected except for 1 wire which is green with a grey stripe (i think it might be remote)
Any help wou
