Just took posesssion of my 2010 V6 convertible with Sync.
Great technology, pretty much got it figured out and working real well.
Decided that instead of keeping my iPod in the car, I would copy playlists to a usb drive and not have to worry about it getting stolen or bumped around.
Came across a thread on an F150 board which states that the Sync module, under the dash has a second USB port that you can install a dedicated USB drive into instead of the one in the armrest storage.
Anyone know where the Sync module, or second USB port is on the Mustang ?
