93V

I just installed my new AVIC-X930BT in my 2007 Subaru STi. Everything seems to work except the GPS and NAV. It started me in LA (I am in NJ) and the map/position never changed even though I drove around for about 10 minutes. Can someone help me troubleshoot? The antenna is flat/level on top of a metal structural piece behind and above my radio. I was getting some satellite quantities but my status always said "sensor initializing". Thanks in advance, Chris
