Thread: Garmin DriveAssist 50 LM crashes and reboots at specific GPS locations

RTL Trap is "Run Time Liberty Trap" and is mostly caused by some minor corruption in the device's non-volatile memory region. Check that after reset/clear nonvol that the device hasn't recreated any files in the GPX folder after the next complete boot cycle.

Some modern NT/NTU map IMG files created from .GMAP folder data using MapSource rather than MapInstall can cause shutdown errors either while actively navigating or when only in moving-map mode. If the map was loaded directly to the device using GarminExpress that wouldn't have caused your issue however.

Another cause of RTL shutdowns/reboots can be minor firmware errors. A fw downgrade to the next lowest version may remedy that, particularly if you did a firmware upgrade just before this problem arose.

@Butters I followed the non volatile memory clearance and managed to eliminate my commute to work 'crash' this morning, however, the commute home 'crash' persists with an RTL error 6E5D8000, consistent with earlier crashes.

You suggested firmware downgrade, but not sure how to go about this?
