Right, I cleared nonvol and did the hard reset with no effect. Have now formatted the nuvi and copied over the backup that Express creates before a map update, i.e .system, gpx, poi, and reports. There was no gmapbmap.img present in the .system folder. The nuvi boots up with the latest firmware, but after the startup screen it shuts down. Figure I'm missing a file or two. Express will download the latest maps to it, but can't see this helping. Webupdater doesn't 'see it'. Anymore thoughts on what I could do?
