    I've been using the CarFM trasmitter from the PDO Store for almost a year now. I noticed that when I upgraded to the 3.1 OS, my iPhone no longer sends phone calls through the FM trasmitter to my car speakers. I can play music with no problems but as soon as a call is started, the audio stops and I can only use the phone's internal speaker.

    Has anyone else encountered this? Did a setting or something change in the Settings menu? I couldn't find anything that would indicate how to fix this. I am pretty much SOL because of a change Apple made? I'm pretty much at a loss at this point so I was thinking about sending this over to their feedback page in case they were unaware that their updates were rendering some functionality inoperable.

    Hopefully someone has some insight! Thanks in advance.

    Here's what I'm using:

    I'm intrigued by your query as I had expected my iPhone (OS 3.0) to output phone calls via the dock connector as you had described had been happening, but it never has! It would seem to be an obvious way of having a hands free without messing around with an additinal bluetooth device. I hope someone can shed some light on this.

    Due to a hardware restriction, voice calls cannot be routed through the dock connector, only the headphone jack. Sad but true.

    Yes, that was my understanding too, hence my comment to the OP.
