Might be missing a setting or something here, but if I plug my iphone 3g onto the ipod cable and have it connected to bluetooth when calls come in they don't come out on the F900bt. I have tried to hit source and then choose the F900bt, but it still doesn't output on the stereo.

If I disconnect the cable, then the call goes thru the F900BT just fine.

Is there a setting or something I'm missing here?

It might be different with 3g but I did not have to configure anything with my 1st gen iphone. The iphone may think you are trying to go through the dock connector for audio and ignored bt

Hmm, that sounds like what it is. I'm surprised I'm the only one who has run into this, no one else uses their iphone over bluetooth with the ipod cable plugged in?

Both I and friend of mine have 3G's and we are not having this problem. Restart your iphone and see if that clears up the problem.
