We'll finally had the chance to test my GPS while driving. Hers what I did - clicked applications - hit maps - left start point alone (Anaheim) - end point: Bakersfield, ca - hit go - hit navagate navigation was on point from start to finish except through the grapevine area (mountains). When it did pick back up it took about 30-45 seconds cause I on some signal other than 3G, E or wifi. Looks as if it was only a G. Anyway....got home turned it off and started reverse directions. Gave me directions and found my location with 7 seconds. So maybe it's not all GPS's. Or maybe I got lucky cause everytime I used google maps at Disneyland it found my location fast.
