I'm trying to play music over USB with ford sync MFT. When I first plugged my SGS3 in, it complained that it could not play protected media. Sync only detected podcast mp3 files on the phone's internal memory. However, all my music files are unprotected m4a's, stored on an external SD card and Sync did not detect any of it. I've played the m4a's before successfully when just loaded on a USB stick. Anyone know how to get this to work?
Yes it works through bluetooth but I like plugging it in via USB so that I can use SYNC's voice commands to play music instead of having to fiddle with the phone while driving. I have not figured out how to get it to work yet.
