Re: Portable Gps
Adrian, yes GPS can be an issue in those urban canyons with all thetoggle quoted messageShow quoted text
multi-path bouncing of the signal off tall vertical structures. However
there must be better technology in the GPS receivers for the mainstream
market, or too many taxi drivers would complain on those same streets. I
suspect that the GPS engine used in the Trekker could be replaced (by them,
of course) with a more technically-savvy GPS engine that uses better
algorithms to calculate and interpolate position where so much multi-path
interference abounds. Most cities today also have a ground-based enhanced
GPS network (called WAAS) with fixed base points usually installed on cell
towers, that significantly improve GPS navigation. In fact, I'm surprised
that Trekker did so poorly in these times when Garmin and Tom-Tom seem to
have no problems at all. My wife and I used a handheld Garmin when we
visited NYC last year, and it was very accurate in describing the street
intersections and locations of addresses.
Your review of Trekker's performance should have caused the makers of
Trekker to go back to their drawing boards and improve the product.

Here in New York city, when I was wanting to buy a GPS device, an
organization conducted a demonstration of the Trekker Breeze. It
misidentified nearby streets and couldn't estimate the distance to
intersections. I was left with a sense that it doesn't pick up the necessary
satellite signal in an environment of tall buildings. I think it's a
question any city resident considering buying a Breeze might look into
first. A friend has used the iPhone (I believe 4S) in Washington D.C. with
more success, so perhaps the app designed for it is a better bet in an urban
environment. This is hardly a good sample size, but the demonstration ended
my interest in the Breeze.

I haven't heard of Captain Mobility before. will have to look it up.
Trekker Breeze is strictly auditory but can't hook up to a Packmate as
you know. IT does give you which streets are in what direction and
more details if you set a route, and will redirect you if you go
off-route. IT's rather accurate and landmarks are excellent as far a
location goes while passing a particular place.
Unfortunately, it seems that everyone has the standard $700 or so when
it comes to the latest GPS. I had to save a llong time to get mine. Do
you have a Lion's Club where you can inquire about a grant? If you
give a good cause to why you need the device, they most often would be
happy to assist in the funds to get it for you. IT may take some
time--sometimes months before you hear back from them--but I have been
successful in obtaining a few adaptive pieces of tech from them. I
understand about thethe finantial cost. Very high for such rather
essential equipment for most of us.
