gettingthere

Hey guys, so installed this unit brand new in my 05 subaru wrx. Wired everything up and even the speed input. The odd thing is the navi won't locate my location. I even tried to manually locate and it didn't work. I moved the navi antenna to the front in plain view and it still won't do it. do I need to drive around?! for how long? did your navi's pick up your location right away? maybe my antenna is no good...
