how can i watch tv, dvd, etc on the rear view with the front panel dimmed out. it seems when i dim the front the rear does the same. i have a z2 with a generic 7inch rear screen. using the rca cables to connect.

Go to the source menu and change the rear to DVD or A/V instead of mirror

i dont seem to have source menu. the 5:1 menu is grey. is it possible that the installer connected it wrong? if so how should it be. i have a z2,xm/nav traffic,ipod, gex-p6400tv, 7"generic lcd screen in the back. also this is all installed in a 2004 peterbuilt.

did you enable the A/V source by any chance? by default it is off.

I believe you should be able to access the source menu by touching the top left hand corner of the screen while listening to a source

i got it. did not know about the left corner button. good to go for now. thanks
