In our market...by the time of the 2006 model...there is no "pairing" button for BT. BT pairing occurs automatically within the 1st few minutes of turning the ignition on.
Below is how it would be done on a 2006 model year (or anything after a 10/04 build date):
{
TIP:
KL R = ignition position 1 & KL 15 = ignition position 2}
- insert key & turn ignition to KL R or KL 15
- within the next 2 minutes...open your cell phone's settings to FIND available BT compatible devices...your X5 should appear as a pairable device...you should see "BMW _ _ _ _ _" where the blanks are the last 5 VIN digits of your X5.
- now enter the X5's BT pass code key number that is on your BT paperwork...and on the BT module itself if you don't have the paperwork
- turn the ignition off and wait 30 seconds before turning the ignition back on to check if your phone paired with the X5
