So ive been having this problem for a long time now and im hoping someone can finally help me. I was on a long trip to Colorado and suddenly my sprint navigation wouldnt work. I exited out of it and when i tried to bring it up again it says and i quote "your blackberry permissions will not allow navigation to function" Well then im thinking to myself all i need to do is change permission to ALLOW and itll be fine. I did all that and tried everything else but still no luck...and like i said this has been a problem for a little over 2 weeks that i cant fix. So if there is anyone out there that had similar problems, id appreciate the help.
