So I finally went ahead with a different purchase of the A4 B8 2013 with the sat nav and all the goodies Does any body have any solutions to getting a speed camera detector working without having to mount it on the dash with a power cable trailing off? My old mercedes I used to have the kenwood double din with sat nav which I could upload speed cameras to, on this MMI Navigation 3G Plus I don't think it's possible. I was thinking of buying maybe a tomtom, uploading the speed cameras to it and leave it in the centre console box where the 12v power outlet is, would it pick up a signal? I don't have a tomtom to test. Ideally it would turn on when i start the engine, and turn off when engine is off. Anybody have any custom solution which doesn't have an intrusive power cable connected to the car dash?
