Hey ctl, Here's a few things to try: 1. Most of the problems seem to concern the A-GPS (using cell towers) rather than the normal GPS (satellites). Have you tried to open Maps in the open and let the phone get a fix on the GPS satellites? Currently, I have no problem getting GPS to work outside, but once indoors, the A-GPS can't get a location. 2. If it's the A-GPS that can't lock-on, first try changing your Location server to supl.google.com from supl.nokia.com. The setting is in 'Settings>Location>Network positioning'. Some users have reported that this resurrects A-GPS functionality. 3. If (2) doesn't work, you can try what I suggested a couple of posts ago: Switch off your N900, and remove/reinstall the battery before switching it back on. One user has reported that the A-GPS functionality will then return to normal using both supl.nokia.com and supl.google.com. Let me know how you get on and good luck!
