Radio and backup camera problem

[HunterLa]

For whatever reason, we cannot get the radio or backup camera to work while we're actually driving the RV. Parked? Radio comes in no problem, but long drives without tunes is hard. It did work at one time, but it's been inconsistent for years. We've made sure it's in USE and hit the reset... Nothing. Thoughts?

I would try uploading a firmware update to your Radio:

What have you done to troubleshoot it?

The radio needs 12 VDC from the house DC buss.

The house DC buss receives 12 VDC from the house battery bank through the USE/STORE switch and the 50 amp DC breaker, or from the converter, or from the chassis battery/alternator through the BIRD/BIM.

So you say it doesn't work when driving but works when parked. Does it work when parked without being plugged into SP? Does the fridge work when the radio doesn't?

Not familiar with your coach specifically, but from your description it sounds like the radio and back up camera work fine when in park with engine running? If yes then it is not likely any interlock relay power removal situation or wiring error related to lockouts. Then the radio and camera quit working when you move shifter into any forward gears.......what about into reverse gear?
Assuming no one has recently modified wiring in your coach, it sounds like moving the shifter is possibly somehow mechanically moving the radio power wiring (+12vdc or ground) somehow to kill power to the radio. Check the radio physical wiring terminations for any loose connections.....both on the radio and on fuse panel feeding the radio as well. Maybe there is a wiring splice (power or ground) feeding the radio that is also physically being moved (loose splice connection) by shifting into gear?
