Thanks catymag, that makes sense.

I cant seem to get these maps working on my GPSmap 62s (FW 2.80).

I have unlocked the Peak District map using Fast Image Unlocker but when I put it on my SD card nothing shows up on my GPS. The map isnt displayed and it doesnt show in the setup so that I can enable/disable it. I also tried the Lake District map (already unlocked according post 1) and I get the same result. I have tried removing all of the maps I have by deleting the IMG files from SD card, leaving the base map on internal memory and restaring the unit with just the Lake District IMG file on the SD card. Same result.

I have had the Discoverer 1:50K whole UK, GB Topo and OSM all on the SD card and working. I just enable/disable which ever one I want to use. I just cant seem to get these ones to be recognised.

Any suggestions would be welcome.

Thanks
