    Doesn't this phone have A GPS? If so, then why do I always lose signal when going under a bridge even though I have 4-5 bars?

    agps is a general fix based on cell towers...Your location could be 2200 feet away....

    Any (and all) GPS receivers lose sattelite connections when *UNDER* something that obstructs its path (a great example is you cannot get Sattellite radio when pumping gas because of the awning, or people in NYC who have bad GPS coverage because of all the tall buildings).

    The "bars" are your radio signal for your PCS coverage, and have nothing to do with your GPS signal.

    Also from the Home Screen click Menu, Setting, then go to Location & Security and see if your GPS is turned on.

    My Garmin Zumo GPS loses signal when I ride through a local bridge-tunnel. It's funny to watch the elevation. At the start of the tunnel it is about 12' above sea level and then it goes down at a steady rate all through the tunnel after I lose the signal, even when I am going uphill going up the other side.
    It's normal.

    Try driving thru Boston an expect GPS to work. I've literally watched the directional arrow spin 360 non stop for minutes on end. LOL

    The OP was inquiring about Assisted GPS. This type is a ground based location acquisition using cell phone towers to triangulate one's position. Which is why he mentioned that he has 4-5 bars of cell phone signal indicating that his phone is in contact with cell towers.

    A-GPS has been in cell phones for many years. This provides 911 responders with an approximate location of a person's location.

    To answer the OP's question, the Motorola Droid does in fact have both GPS and AGPS. AGPS on the Droid is activated when you place a 911 call. It is not utilized for navigating.

    Taken for the Motorola website:

    No, google maps and other apps (locale for one) have access to agps as well. It is very innacurate when compared to gps though. I turned off gps then opened google maps and it thinks that I am currently in the middle of the Wal Mart parking lot about 500 yards down the street from where I am sitting now.

    Haha, AGPS said I was a good 1mi away (straight line) from my actual position and on roads its about 3mi.

    That's where I was actually. I was coming back from the TD Garden and my car GPS was working fine, while my droid couldn't find GPS signal... I'm kinda let down by this.
