This too has happened to me - Done the official garmin update last year and sure enough the map has expired (in March).

Questions:

1. Does this Garmin Update ONLY affect unlocked maps?

2. Has anyone tried to use an unlock code generated with Jetmouse with this garmin update? Does your map still work? (i.e locked map with an attached UNL file)

3. Will Jet mouse v.1.5 generate valid UNL codes for maps with FID greater than 2200?

Thanks all x
