I tried an external receiver for a while (it was the one from Garmin called the “Glo”) and I never noticed improved accuracy or greatly improved battery life. The question is how iOS uses such a receiver, does it indeed completely turn off the internal receiver if an external receiver is connected or does it simply use both signals. I found the fact that I had to remember to keep the external receiver charged and to bring it more trouble than it was worth.

One such model is the Dual Electronics xgps 150e ($100), and a slightly faster model which allows 5 devices concurrently to pair with it is their xgps 160. Both the much improved battery life on the phone, and the much better accuracy sound interesting to me, so I wondered if anyone here had tried an external gps receiver? They are also supposed to be much more sensitive, working in downtowns full of buildings, inside houses, and other places where the phone’s accuracy is pretty bad (sometimes using only triangulation off of cell towers, and not able to use GPS at all). These models I mentioned come with a rubber holder which you can strap to your wrist or a strap of a bag. What do you who constantly use some GPS navigation program like Blind Square or Nearby Explorer think about their current GPS accuracy and/or battery life? Do either need improving or is the first ok, and the second fixable by carrying a spare battery? Thanks, Chip Orange -- The following information is important for all members of the V iPhone list.
