I am running OS v4.5.0.77. I can run bbmaps and it seems to work ok (finds 8 satellites) but an actual map never shows up. The screen stays blank no matter what I do. When I run the gps and click to find my location it has an arrow and point that says you are here but no map or address. Same thing happens when I get directions. I tried a battery pull and that did not help. It's probably a simple fix but I cannot figure it out. I would appreciate any help!
