Maps which you can save on memory card.

Hi,
does anybody aware of any company provide the maps which we can save it on our expansion memory card so we donot need browser/ dataplan?
if i am not mistaken i think both BB maps and google maps need data plan on your phone?
i have BB pearl 8100
appreciate any help on thios issue.
my provider is rogers from canada.

I haven't heard of any software that can do this.

Have you try "TrekBuddy" (trekbuddy.net) Its great, but it doesn't work on the latest firmware of curve (175)
