I have the same problem as coweyeboy, and I followed the instruction to the T.
1. I grounded the parking brake.
2. I added a SPST switch between the grounded cable and the parking brake wire.
3. I disconnected my VSS, pink wire on harness.
4. And finally I reset everything I could find.
It works for a while and then the video goes away and I get the “Viewing while driving warning†and I lose picture from the DVD.
After reading the success others had I think I may be doing something wrong.
HELP!!!
