could you be so kind to advise where this fuse can be located?

No Martin looks like it's not a fuse, because I can run the Pairing process...but without success.BT Module don't want to see the phone...
It apprear like:
1. or mobile don't see the BT Module (shows No devices found)
2. or mobile can see device, but after dialing CORRECT password - shows Invalid Password
i.e. both side working but do not want to connect.

BTW I have checked all fuses in rear compartment - OK, checked fuse in the glove compartment (Telephone Fuse#7)- OK, pluged un unplug almost all connectors in BT line.

PS.<<<desperately awating for you advise>>>

I would try to remove the battery cable and try to replace with a new one. Jump starting a BMW is a BAD idea. I have seen many things get hosed up with a low or jumped BMW

Martin

will try right now...

Davud, when you said you solved the on-off-on-off problem by clearing the sms did you delete sms from the phone or from the screen of your bmw?

I am not sure if I delete the sms from bmw monitor, will they actually remain in the phone inbox or are going to be deleted as well?
