Hi everyone, thank you for the info on this forum I ended up buying a 2005 x5 4.4i.I been searching for info on back up camera with out tv module and can not find any info. I have navi and want to hook up a back up camera but I don't have tv. I search by the battery section to make sure and I don't have it. Can you help, can I tap in back of navi monitor or behind the navi player?
