Finding the PIN to pair My iphone with 2006 BMW 750i.

i bought the same car few months ago and i was also trying to connect bluetooth so i found it on the bluetooth passkey card, it came with the owners manual. my code is 3596 you can try that if it work for you, good luck

I have the same car. The dealership wanted to charge me $155 to go into the computer and give me the passkey.

One of the techs just told me how to find it myself:

Inside the trunk, on the left side behind the DVD player, there is a box that sits at a 45 degree angle. Right above that box, there is a box that is shaped like a VHS tape. Unscrew that box and on the other side you will see bluetooth PK: and your four digit number.

That saved me $155 dollars and now I can talk hands free through my car.

That one is 128.000.00 dollars.
