Do not know if this is at all possible. Is it possible to reprogram/update the Garmin by attaching some repair device to its motherboard?
My Garmin 50 LM will not get past "loading maps" and it is not recognized by PC.
When I connect the powered-off Garmin to my PC; the Garmin wakes up but instead of going into Mass Storage Mode, it shows the progress bar. The Garmin does not appear on the PC as a drive.
