I recently updated the maps in my RV760LMT and then installed the latest Low Clearances POI files as I have done many times in the past. The next time I rebooted the GPS, it went into a constant reboot cycle at the "Loading Maps" screen. Garmin had no cure for this condition and I was forced to sent the failed unit back for exchange. The Exchange unit failed in the same manner. I have received a third unit, which I have not mounted the Low Clearances POI files. Contact with both Low Clearances and Garmin have not been too satisfactory. Garmin Customer Support has been able to reproduce the problem and admits that there isn't anything wrong with the Low Clearances files. I started working this issue in late June and have still not received any satisfaction from Garmin. Has any other Garmin user experienced any issues like this, or is my experienced unique? I've seen many other posts on GPS forums with the topic of crashes and rebooting at the "Loading Maps" screen, so I have trouble believing that I'm alone in this.
