THought I would resurrect this thread. I get exactly the same as DLClarke (Searching... then Activate Phone after 2 mins wihtout anything showing up on BT enabled iPhone). Did he, or anyone else, manage to get BT working? I seems odd that it's saying "Searching" on the display then switching to "Activate Phone". This to me would mean that it is going into auto pairing mode.

Or is "Searching" mean something else?

For reference I have a 2001 E53 which I have retrofitted with a UK TCU. The x5 used to have a BITII system so I changed the wiring on the 54pin plug as per one of the posts on this board.

Cheers
