CountryB thank you, tried reset and it didn't make any changes. But after troubleshooting and testing the Intellitec Video switch board, it came down to the Kenwood monitor in the dash; it has two inputs one displaying engine date and the other displaying cameras. we removed the engine data from video 1 and plugged in the cameras output to video 1 instead of video 2 Yahoo
, the cameras work. As far as we can tell the video 2 input isn't working on the Kenwood Monitor. I'm thrilled to have a back up camera again. As far as engine data we already have a small digital display built in the dash, no need to have it displayed on the large Kenwood monitor. We bought the coach used and its obvious some camera / monitor changes had been made.
