That doesn't sound promising, however it may need to be outside depending on how many tall buildings are around you. I assume you can't open the window or the weater is not such that it would be advisable. Unfortunately, I am not familiar with the display for GPS Info but I would think to prove whether the GPS will work, you need to take it outside. You should not need 2 hours; under normal conditions 5 minutes should suffice. Even if the sky view is heavily blocked by buildings, you should see at least one satellite.
