I'll try that. If it doesn't work, I'll definitely get in touch with you for that file.Time and patience is the key. Let car sleep for 10 minutes before putting back in run state. I've watched a few take 30 minutes or more before finally loading. Do this 3 or 4 times if needed. Once it does load it will work as normal.
If that doesn't work I have a Garmin file for you I use for unbricking. gupdate.gcd (9,107kb)
