Hey, So I have an '11 GT with SYNC, and I have a question about the USB port in the armrest for playing music. I bought a standard PC/Mac USB thumb drive...8GB...and loaded about 700 songs from my iTunes onto it. I did a straight copy, so some are MP3s, some are AACs...whatever. When I go to play the songs, like speaking "play all"...it sometimes says "Bad Media" (I think) after playing a song...and then there will be a pause as it goes to find another song. If I watch the display, I can see the "bad" title/artist show up for a split second, then goes away. If I speak "play track" by that artist, it will play. Using the "next track" button on the steering wheel will sometimes get a song that plays, or the message "bad media" as it searched for something it likes. Basically, it's kinda flakey. If I tell it to play artist "Van Halen" it will play all the tracks that I have by VH, but if it's just playing random music, it might skip over one of those songs because of "bad media." Now, if I do Bluetooth streaming to my iPhone 4, it works like a champ, but you can't call out specific tracks/artists/genres using the streaming option. I might try connecting my iPod shuffle to the USB port and see what happens there. Just wondering if any of you guys (girls?) have had this experience with your SYNC and USB port/drive.
