So my wife has the S and the 2.3 update on it. If I open Google Maps and tap the GPS icon, it locks right on and finds where we are. The icon stays solid in the status bar. From there, if I hit the dropdown and choose navigation, it then goes to Searching for GPS and the icon in the status bar starts flashing. It just sits like this and never is able to lock onto the GPS signal. I've tried toggling GPS on and off, tried rebooting the phone, etc but nothing helps. I don't understand why Maps can lock onto the GPS but Nav can't. Anyone else have this issue and have any idea how to resolve it?
