Bluetooth Pin Numbers/ Passkey number-- 2007 328xi and 2006 750 Li
Despite what has been said: if you are searching for the Bluetooth Passkey number, it can be found by lifting up the plastic access panel in the 328xi trunk on the driver's side.
Although they talk about a PN or pin number for the 750 Li also, it is actually a four digit number shown as PK on the unit that is hidden by the felted trunk finisher that has to be removed to read it, and if you don't want to destroy the liner, you have to remove the box hanging from the package shelf, which is attached by a sliding nub. You will get better access.
On the e 90, 91 and 92 it is on the top of the aluminum heat sink, ans is shown as HS and again is four digits. It is on the unit under the plastic tray. It requires no removal but is upside down, a tough read.
I can't believe they change the letter designation, but it is german made.
