Sorry, does it show your aproximate location (from cell tower triangulation) or even that it does not show either?

A) If it is not even showing your approximate location then do this
In Google Maps select Menu -> Help -> Settings -> Enable My Location (You will need to scroll down to see the Settings)

B) If it is showing your approximate location (already or coz you did the above) then do this:
1. Have on Location services On:
Options -> Advanced Services -> GPS -> GPS Services = Location ON
2. Instantiate GPS satellites outdoors in an open place:
Options -> Advanced Services -> GPS -> Menu -> Refresh GPS.
3. If your bearings are refreshed then go back to Google Maps and press 0 (Zero).

Hopefully this helps
