Ah... SYNC, oh what fun. The in-dash port worked once for me; now when plugging in a flash drive, the activity indicator just does one quick "flash" like there is a bad connection. Bought a plain cable and an adaptor thinking it's just a bad dash cable and same result. Plugged plain cable into USB2 and the drive lit up and functioned perfectly. Wanting USB1 to work, I thought an update might fix it--nope-- it just deactivated the USB2 voice command (hint hint, if you're happy with your current version DO NOT UPDATE; the chick sounds like she has marbles in her mouth when saying "Bluetooth Audio" as well).
