Aftermarket headunit malfunction
#1
Anyone there having similar problem. 

I had recently installed rear view camera that fits where the rear light is, just above the number plate (Astra elite 2011). All wires set up and camera triggers on when in reverse gear.

The problem - the button on the car stereo faceplate (Volume and option) & steering wheel control works perfectly prior the use of rear camera. Once I active the rear camera via the reverse gear the screen views the rear and after disconnecting the reverse gear the camera turns off bringing to normal screen, but I cannot use the volume and option button in head unit (Sony XAV AX3005DB)nor steering wheel. Only home button works in the head unit, the music can be changed via the touch screen.

Anyone have any idea what is causing this? Seems like something gets switched off inside the head unit.
If I turn the ignition off and on again, I can use the volume, option button and steering wheel function.

Not something I've seen anyone else suffer with.

Could be worth seeing if there are updates for your radio.
