Would take 20 to 40 minutes to lock, and would lose signal in heavy tree areas, and large coverings. No skyscrapers here, maximum city ordered height is 13 stories I believe
As soon as I stuck it outside, instant lock on cold boot, and reception in the garage with the door closed, I never loose signal. 2mm of metal sure does make a difference!
My experience exactly. That's why I'm considering an external antenna. I can't figure out how to stick that GPS mouse (Garmin 18) outside. It is in my dash right now, at the skightest tree/building, I lose signal. Outside the car, perfect, it takes a very narrow street with tall buildings to block it. The roof is the best place by far, period: number of sattelites, speed of locking into them, precision, etc.
