Thread: BMW Navigator VI

@TomasTT
Sorry for late reply.

Your Navigator has a corrupt file onboard that is preventing a complete boot cycle. It must be removed by first loading a MODIFIED *.rgn file in preboot to re-enable Mass Storage Mode (see this: [Only registered and activated users can see links. ]); then remove the offending file (or if absolutely necessary, re-format using only [Only registered and activated users can see links. ]); and finally flash again with the ORIGINAL *.rgn in preboot. Read the complete guide here: [Only registered and activated users can see links. ]. It's the same procedure used for your Nav VI.

Although it might be any recent file added by GarminExpress that is corrupt, you might have a clue depending on what was being updated at the time (a GCD firmware file; an IMG map file etc., etc..). Post again here if you need additional general assistance or in one of the above linked threads if more specific help's needed.
