Evening. I have a flip out screen Pioneer AVH head unit in our Westfalia James Cook. Plays music etc etc 2 cameras, one connected to the reversping port of the head unit and comes on when reverse is selected. The other camera is permanently on and is connected to the AV port of the head unit. With AV selected That gives a good view behind and to side when driving but because it utilises the AV port , no music can be played! Now that we are all grounded and have tinkering time, I am wondering if there is any way of wiring the permanently on camera that will enable me to play music? Otherwise can only play music when stationary and I switch out of the AV mode. Any of you electronic whizzkids out there have any ideas? Treat me as an idiot please!
