So I know this is yet another random shutdown question but please bear with me. Montana 700i has been glitchy before but never so chronic. Since update yesterday when it is in the cradle it cannot stay on for more than two minutes. Device cycles or shuts down for extended period before rebooting. Device is totally useless. As I mentioned it has up to date software and maps and does this endless cycle of reboots whether navigating or just switched on so I can see the map. Cradle is OEM cradle. Mounted on BMW motorbike with stable direct power supply. Any ideas - factory re-set etc? Please let me know.
