So I am using my Droid through my car bluetooth hook up but the music is so weak I have to crank my stereo up, but I can get turn-by-turn navigation and listen to music. I tried using the USB hookup but I couldn't get the turn-by-turn navigation to come through the speakers while I was using the USB hookup. The music came through once I "mounted" the Droid and sounded great. Anyone else have this issue? Did you find a way to run it through the USB listen to music and get turn by turn navigation? I did some research and I'm wondering if my car stereo has a headphone jack... that may fix both issues. Thank you for your time.
