Beth Probably the most inexpensive gps unit which is accessable is maestro
with Trekker. It gives you the very basic of where you are and automatically
announces cross streets and it alsohas several million points of interest in
it and allows you to create routes. It is pocket size and has an offline
browsing mode.
Ok you're asking what's the difference between that and the Braille Note
gps? You can't program it the way with a Braille Note GPS. With the Braille
Note GPS you can ask the program to give you heading and distance for
multiple items, e. g. a set destination and the nearest intersection, or how
fast you are traveling along with how many satellites you are tracking or an
intersection plus speed, any way you like and you can also obtain gps
information on the Braille Note using latitude and longitudes.
So that is the difference between that and Trekker.
But yes, the Trekker can be bought either as a stand alone program or on
Maestro.
