Hi W1N
No to sound stupid, but I have the same radio.
Do you get any information on the screen ?? Or is the screen Black ??
If you have like "normal" radio control or dvd control then it's just a matter of selecting the right view mode, you do this by pressing a button on the head unit.
I don't remember what's written on it right now, but I do believe it's a little silver/grey thing on the lower left side off the head unit.
I will have a look tomorrow, when I'm installing the same unit in my new Hummer (collected today
)
It's a great unit, and there should be no problem with it
