Hello All, I have the F90BT w/firmware 2.0 and a Motorola Q connected via Blue Tooth. I could be listening to FM or MP3s on the SD card and then a call comes in. Everything works great until I end the call. The audio doesn't go back to which ever source i was listening to before the call came in. I have to restart the car to get the audio to come back. Is this a problem with my phone or the HU?
