Thanks for a LOT of help from Jochen, and only a small bit of help from me, J A M E S on e38 bimmerboard.com has tested out the digital TV system on his 750iL. See his posts there. He has tried 2 different units, one 12 volt and one 9 volt. We put together a cable so the car antenna could be used. It runs through the video module AV input. Jochen made it all work! The car is in the LA area.
