I am reasding up on the geocaching and am completely clueless. However when I open up the maps on my BB and go to GPS then options it says the default is BLACKBERRY MAPS NA......does NA mean north america or does it mean NOT AVAILABLE? As in do I have a problem I need to fix? I tried to set the gps up to take coordinates but can't figure it out.
I don't believe that the BB Maps can tale coordinates. But I don't think the Sprint Nav can either.
Perhaps there is a third party app that can do what you need.
Good Luck!
There are several free GPS apps... take a look throught the GPS forum here and you will find all of them talked about, some good, some not so good. At least they are free and you can try each one and see if it has benefit to you.
