Ditto above...the older units are referred to as ULF....but from the Oct/2004 build date up...if you have BMW ASSIST or the premium pkg...then you got the newer TCU unit (with voice recognition) which you pair by following the instructions below. You will need the PK code (pass key code) from off the module...and this is what you enter into your smart phone once you've opened it's BLUETOOTH setting to find your X5. You have two minutes once you've turned the ignition to position 2...when you go to your smart phone to search for BT compatible devices...your X5 should appear as "BMW_ _ _ _ _" where the blank spaces are the last 5 digits of your VIN.
Select your X5 when it appears on the list on your smart phone...then enter the PK code.
Tips (aka what I did):
- KL R = ignition position 1 & KL 15 = ignition position 2(position 2 worked for me)
- I never saw "Bluetooth pairing" on the Nav screen...I just went to my smart phone and searched for new devices...and saw BMW24133 (which is specific to my X5 because it's the last 5 digits of my VIN)
- I then selected BMW24133 and was asked to enter my 5 digit PK code
- Then I saw "paired" appear on my smart phone below the BMW24133
- I then shut the ignition off and waited 30 seconds
