I recently performed an update to my Garmin GPSMaps 62s, and shortly thereafter the unit began shutting down unexpectedly. Sometimes the unit would shut down whenever MAP was selected, and then it seems to switch to when VIEW GEOCACHE was visited. Garmin had me do everything but smash the unit, yet the only thing that "worked" was doing a master reset without and geocaches loaded! Obviously that won't work! Now they want me to send them the unit + 0! I'm hoping someone else might have had this issue. Thanks in advance.....Michael
