Sorry about bad information! More Info. Car is E83 09/2004 with BMW Professional nav and BMW Bluetooth (Original phone adapter in middle armrest is for Nokia 6310). I tested it with Nokia E66 and couple older Nokia model and all phones works same. Car connect perfectly to phones and phonebook and SMS updated correctly. I can call and answer calls and I can hear friends speaks from speakers but they can't hear me. Even if I press speak button in wheel I can't use speak commands but I think that I don't have that options in my car?
