I have followed the directions to the T and the stupid thing will still not update. I am using the USB port with the correct file, but it keeps popping up with the message that I need to insert an update stick with the correct files. I HAVE!!! I am very tech savvy and can build a freaking computer or completely reformat a hard drive and reinstall everything, including drivers, and can't get this dang car to update. Is there a trick I don't know? Is anyone else having this issue?
