OK... I now have Sirius S50 installed in my 328...now I need to install in my wife's X5. I have asked a few times and really appreciate the instructions on the direction in which to proceed. Now I am at the point of purchase. To remind you. the X5 is a 2002 with Nav. I want the OEM setup. I went to the dealer and he quote me about 400 dollars for what he thought it would take. I described to him what I thought I woul dneeed. This included the module in the spare tire well , the extension wire, antenna, and the bracket. Is this correct. Please let me know. If this is correct, does anyone have the part numbers to make sure that I receive the right parts and lastly...does anyone in Atlanta or nearby know of a place to install. Thanks a million guys. This is a surpise for my wife's BDAY. Hope it works out.
