I've been enjoying Ptunes with the Yahoo Music service on a Treo 650. Works great. In my car I use an FM xmitter to get stereo sound and have been using a 2.5 to 3.5 mm adapter I purchased at the Palm Store (looks like the one made my Sedio). I also have a built in bluetooth system in the car which integrates well with the 650; favorites show up, voice dial works, callerid is there, etc.

The problem is when listening to music via the FM xitter and a call comes in, audio gets lost, it won't play via bluetooth or FM and the remote party is unable to hear me. What I have to do is yank the 2.5 to 3.5 adapter and then I have call audio via bluetooth. Same thing when making an call. After the call music resumes just as advertised by Ptunes.

Has anyone seem something like this? I suspect that the adapter may be to blame (for example if there is no adapter and the music plays from 650 speaker then all is good). I appreciate in suggestions.

Thanks, -Juan
