I seem to be having a problem when I connect my RAZR to car stereo (Pioneer DXT) it connects perfectly, but then it DOESNT play MP3's...? it seems play -some- .wav files (like the navigation girls directions: Take a left, Keep right at the fork, etc) the stereo has played them in the past. Could this be a setting, or the OS that is having the issue? Recently I went back to Moto ICS for the RAZR, so the stock version, but still rooted. Any suggestions or help would defiantly be appreciated.
