Yeah, I thought about that. But on a pc, you can select boot device. They should give you the option so you can leave your usb stick plugged in or ipod or whatever w/o it playing on startup. It would very easy to make the last selected device (AM, FM, disc, sirrus or usb the default device on startup for the entertainment portion and still have the mft itself look for a usb device for updates on startup. All they need to do is include an .ini or .exe file on the usb stick with the update and have the mft look for it on startup, if it is not found then boot into last selection, that simple.
