I used FIU in PC to unlock the map, then saved the unlocked map to "Map" folder (which sits in device memory not external memory). It worked because my device recognises the map (shown in "Info" under map settings).
However, I've just arrived in China and I have been trying but my Nuvi 1250 couldn't acquire satellite... Anything I can do to fix this?
Thanks.

Btw, just to add on after some thought... Could the fog here have caused my device not able to locate satellite??
