i am in direct talks with with the factory, they are not even on ebay.. they sent me video of their system but i am not sure if i am allowed to post it on utube... the video is of the system in operation... granted, they use toyotas and whatnot, even though they claim that the X5 is not a problem, and even sent me pics of the cameras for the E53 - but the two versions of the rear cameras that they have are both incorrect - one is the license plate camera that does NOT fit in to the light opening, and the other one is integrated into the trunk opener - the whole rear thing is an integral piece with internal circuit board and I am not sure of the handle part can be separated...

I did modify the license plate light camera for my car as documented in one of the rear camera posts but it is NOT plug-n-play...

I will let them know abou it...
