Hi
I just upgraded Europe map by using Garmin MapSource software. After that I am not able to start my GPS nuvi 310. Now it starts and it says "loading maps" and if no power, it switches off and with power, just loading maps. I have tried all the hards, soft resets but this has not improved things. The problem is the pc does not see device as a drive. I have tryed Pre-boot and press reset. Battery is fully charged. Thanks.
