As long as you have your GPS enabled, your phone will default to GPS, not wireless. It can take a few seconds (up to a minute) for the GPS to lock, but it will eventually.
That's what it sounds like. It seems like the OP doesn't realize that GPS is GPS. However, a GPS app may require data for maps and so on. The GPS receiver and the app are 2 separate entities even though many people seem to lump them all together. The GPS receiver only needs line of sight to the GPS satellites. All it does is provide your location (latitude and longitude). Everything else is supplied by the GPS app.I believe the problem the OP is having though is Google Maps needs a cellular signal to download the maps info to display.
