Adding 2nd Video Source (TV TUner) to Factory NAV-PRO

[X5_Rob]

I just purchased a new to me 2011 X6. Since the X5/6 are so similar posting over here as the X6 forum doesn't have much action... I can watch a DVD on my Factory NAV screen and have the backup camera/top view camera's... I want to add a digital TV Tuner.. I haven't had much luck in determining if the factory setup has an additional video in or if I can add an OEM or third party module to add an additional video source.

BMW equips most X's with TV Tuner in almost every other region of the world but NA.... I gotta think the wiring harness is not different for NA and the TV Tuner is simply not installed for whatever reasons they don't do it over here..

I know I can add the NAVTOOL which will give me additional video in but really looking to stay with the stock setup....

Anyone Familiar??

Thanks!
Rob
