Can anyone advice me if 255W is able to load more than 2 maps at one time? I only can load 2 maps at a time:
gmapprom.img - Aus & NZ Map
gmapsupp.img - SG & Malaysia Map

I've try to add in Japan map with the file name gmapsupp1.img
, but no such map found in my GPS map info. Anyone can provide me some information & advice?
