Hi guys
I have 2, 3.5mm jack sockets for AV in and AV out in the rear of my
X5 centre console, my X5 has TV, Satnav, etc.
Does anybody know how they work?...if they work?
Could I use it to imput a Digital radio?
Also there is a TV button next to them, whats this for?
I can't find any details in my manuals.

Thanks for any help
