Hi,
I just retrofited BT on 2004 X5 form bimmernav . But it does not works on Nokia 8800.
2 month ago I upraded BMW software,as dealer sad by latest version, but in that moment I had not BT.
Does Car software upgrade upgrades BT modul software too?
If yes, maybe I need to upgrade car software one more time with BT installed.
Have some one succes on Nokia 8800/8801 with BMW BT?
