I don't think my problem is with the auto switching-my problem is that the boxes I have tried-kufatec and dietz - are not compatible with my RNSE (glossy surround)
Think the only option I have is to buy the expensive R8 reverse cam module for it to work.
Please correct me if I'm wrong!
it looks like when you turn the ignition on your rnse is looking for video input of some type, a dvd player for example. do you have more than one video input allowable on your interface unit, is yours ima basic or basic plus?
