TrekBuddy is one GPS app that allows you to download maps to a media card. It's intended for use in areas where you don't have a cell signal.
There is a Garmin app for BlackBerries, but it requires a data plan to download its maps. It does not store maps on the media card, or come with any preloaded maps. It's $10/month, or $99 for the life of your BlackBerry, non-transferable.
MOD NOTE: I'm moving your thread to the GPS and Mapping Forum, where it's a better fit.
