I often use the N900 builtin FM transmitter to listen to music while in my car. The music stops playing when somebody calls me but I can't hear anything. The caller can hear me, but I can't hear him.

Last time this happened I switched back to the media player and switched off the FM transmitter and then back to the phone application and all was fine: I could hear the caller.

Does the FM transmitter really not switch off automatically when I pick up a call? Is this a bug? AFAIK this used to work in the past, maybe pre PR1.x.

Thanks for your advice.
