So I was in the truck cleaning up some wires that the PO had tapped into for speakers and I found this plug. I think it's for the Bluetooth antenna? My BT isn't working and fails to connect? The silver box is present with another purple plug.
So Does it go to the BT antenna?
If so anyone have a part # it's a 2006 x5 3.0
Thanks
