I don't know if it exists but the RNS-E supports switching the source through VAG-COM. If someone would build a black box which would send a certain K (or maybe even CAN) signal when in reverse, this project would be possible. Of course, when driving faster than 5 mph the screen will go blank. But that's another issue.NSX JR said:I've done a search on this, but have not found if there is a way to have a rear view camera that automatically activates when the car is in reverse gear. I realize that I'll need the 1417 and a camera to make this work, and by doing this you could activate it by selecting TV as your source. I'm just wondering if there's any way to trigger the camera through the reverse switch in the car. Thanks.
