Can someone tell me which stable rom has its car bluetooth rom working?

Hi guys!

Have someone met the same problem as me? its so frustrating. im always having problems with the official miui rom or some of our beloved developer rom. Either it doesnt save the bluetooth info in my car (ie everything i switch on the car, i need to rekey in the password) or the bluetooth just switch off every few secs..

Perhaps I havent tried all the roms, but can someone tell me which rom is working for the car bluetooth? would really appreciate it!
