Hi all, I have bricked Nuvi 5000

1. As mentioned it's a Nuvi 5000, G7ToWin don't show which FW but HWID is 1830
2. Suddenly device can't startup properly.
3. It seems to boot ok, but when finished loading map, it's stuck at screen reminding that maps are more than one year old and needs update.
4. PC can't see the device (only in preboot mode device are shown in device manager as "Garmin USB GPS")
5. Tried hard reset, and loading new map from SD.
6. I have all Garmin drivers installed.
8. I haven't tried Garmincure3 Tool etc, as I can't find any GCD files for this device,
so only have "Nuvi5000_410.exe" and "Nuvi5000_regionfileonly__410.rgn"
9. I can easy enter preboot mode.
10. Don't have NV backup.

Any help would be very much appreciated.
