New bluetooth module
 

Where can I buy a bluetooth module for my '04 X5 w/nav? There is one there according to the dealer, but it is not functioning. They did not even offer a solution and when I asked the simply said it's too expensive....I left it at that, but still want it fixed any suggestions?

Thanks in advance...

The cheapest path is to buy TCU part number 84.10-9 195 455 from an online dealer like Silver Springs BMW. They sel it for $338. There is a core charge, which means you need to send your old one back.
