Access to A/V Input in the Idrive
 

Greetings all,

Does anyone know how to access the A/V Input to the Idrive/Nav system? I am looking at retrofitting my car with a rear/backup view camera. All the cameras have A/V input plugs and wondered exactly what is involved with this. :confused:

I also dont want to void the warranty by too much surgery.

Thoughts?

Thanks all and happy motoring!
