I'll check into it.
I know I've seen many BMWs with aftermarket "toys"....tv screens, cd changer, all that you say. We have a 2003 M5 with all those aftermarket stuff....We (or the customer) had them removed BUT, the audio/video interface might still be there. If it works for an e39, it's got to work for an e65.
I'll get back with you on this one. I'd like to see what other people have to say about this. Specifically Rooz, he knows alot about audio stuff.....as well as Komodo. He had TONS of aftermarket stuff on his e36 (Computers, PS2, DVD screens, on and on.)....he should know.
But, other than that.
Is your radio is working....CD player? CD changer maybe?
