Nick the problem i have was not with the VIN being incorrect(which was auto-detected by maxisys) but AUTEL software was not correct for that VIN and still has not been fixed so if anyone else try,s to update the radio with enhanced Bluetooth enabled they will lose it also.
don't believe me be my guest and try for yourself..... i have been around long enough to know if it was my fault or a software issue no tool is perfect but the maxisys now has more than its fair share of errors.
