OK, took awhile to get around to it. Followed instructions that came with the Ford USB. All was well thru the reboot and wait for about 20 minutes or so, 40 minutes later reboot had not completed. Turned car off, unplugged USB. Instructions said May have to do a master reboot. Started again and Nav, radio, etc does not come up to allow a master reboot. Gonna let it rest overnight and retry. Anyone else have this problem?
