Read the yellow sticky at the top of this section. It has reviews of most of the map applications for the BB. There are only one or two that do not require a data plan. And from what I have heard, they are expensive and not very good. But be your own judge.
I think Garmin also has an app that stores the maps on the SD. Not sure which cover your part of the world however. That could be an issue.
