I've read numerous threads on the topic and am still really confused as to where the PassKey is located and how to pair my phones to the X5 i just purchased. I know from what I have read that the BT module is in the trunk area near my navi system, however, I cannot find it

. I have also just tried to run through the pairing of the phone by turning the key to the first stage before starting then pushing the R/T button on the wheel -- it pulls up 'activate phone' but never asks for a PassKey...Assuming I find the PassKey, what else needs to be done??
Dazed and Confused looking for help.
THANKS!!
