I am using my Droid 2 Global as my "iPod" via iSyncr. In the car, with Bluetooth on, it automatically plays via Bluetooth. The problem with this is that I can only adjust volume via the phone itself. (In my car, the car stereo volume and on/off do not affect sound coming through Bluetooth.) I would like to set my phone such that music plays through the wired audio jack, but keep Bluetooth on for phone calls. Is there a way to do this? Thanks very much.
