Thnx for replying.
I did read those threads. Im finding it very confusing for MAC users. The info. gets mixed a lot with Windowns.
From what i could understand, some IMG Unlocked maps, cant be openned in Basecamp. There are, however, aplications that alow me to do that (like JaVaWa Device Manager). Is that right?
Regarding the Mapsource Unlocked files, i didnt find much to go on (on a MAC).
