AV1 input problem in COMAND
I installed digital TV receiver and decoder box for my W203 '06 COMAND. Connected to AV1. Got a strange behavior... if I move from AV1 mode to other mode (analogue TV, radio, or CD or Aux), I will get blank blue screen on AV1. I still can get audio, but no video. I have to switch off the car, re-ignite, and restart COMAND to get the AV1 video and audio back.
Anyone can advise what should be looking in the COMAND setting?
