I have a 2007 BMW X3 and I just installed a factory OEM navigation system. Everything is working as it should.

Unfortunately, my XM receiver, which worked fine through the original in-dash radio, is no longer recognized by the navigation system and therefore does not show up on the screen. Is there any way to get the nav system to recognize the XM receiver? I would hate to have to switch to a BMW Sirius receiver.

Thanks for your help.
