Dear Audiworld contributors,

Cannot figure out what triggers issue - seemingly randomly backup camera and sensors stop working when put in R - P4 switch beeps and blinks on IP console. Restarting engine, switching to P and back, trying to turn off P4 don’t do anything. Issue sometimes resolves by the end of a ride, sometimes continues for a couple of trips (engine off/on).

Any idea where to investigate?

Thanks! If I missed a previous thread, I apologize, searched and didn’t find an advice.
