OK thanks a lot so if I am understanding your post then this should not be connected?

Update Port only?

Like I said if I connected it I lost all iDrive Functions, even after a hard reset

Disconnecting the Port and hard reset everything came back

So to be clear then this should be or should not be connected together on the back of the cover? I guess I can go to the other X5 that is the same model/year and check it...

thanks

I only thing that has never worked but is present is the BT. Would like to get this working just for the phone connectivity.
