Hi
If you have time:
I am a new user trying to update an old go720. I have a 9.5 navicore and am currently using an 8.5 map: North America 2GB.
I added new maps on an SD card, after patching with FastActivate several 10xx.11308 series; the maps will not open: 'You cannot use this Map' then lists the name and meta number. NAV2 G0 is listed as compatible. What might be wrong?

Your navcore should be updated to 9.541:
