Blacljack II GPS help

[Guest rbcardz123]

Ok i just got my bj2. Im leaving on a trip tomorrow, and i would like to use its gps features, only one problem. Where im going doesnt allow data reception. ive unlocked it to use live and google maps and those work fine, its just that i cant use them where im going because they require downloading maps. Are there any free gps programs that will work on my blackjack with predownloaded maps?

Thanks!
