Same problem here too; trying to pair my Blackberry7100 with 4.8iS and the phone did recognize the vehicle (BMW82136 shown code on the mobile phone), but the X5's screen is stuck on "Please Wait" and that is it. Gave up and took it for early Saturday drive. I will play more with buttons tomorrow and that PK(passkey code) and R/T buttons should work their wonders, hopefully.
Any input would be appreciated
