sorry I can't help you with all your needs. However, I can tell you
that my cheapie Wal-mart GPS hand-held I bought in 1996 for $138 works
perfectly everywhere in Mexico that I have gone. So, I can say with
some confidence that any standard US based GPS system will work
perfectly in Mexico, as far as telling you where you are.
Maps are the problem, since I don't know any maps of Mexico that are
not full of errors, so I sure can't tell you where to get good maps.
And, as far as the car systems I have heard about which can tell you
where the nearest restaurant is, my guess if: FORGET IT.
By the way, a couple years ago, my brother-in-law, who is an inspector
at a sugar can ingenio (San Miguelito in Cordoba) asked me to teach
him and several fellow employees how to use a hand-held GPS, pretty
much like my little Garmin. So, we had some classes.
They got a brilliant, young female engineer working with them. The
gov't ordered them to survey all the sugar lots, which involves some
hundreds of irregular shaped lots. she wrote a program, the
inspectors run around the lots and at every obvious point, mark a
waypoint. They download it into her computer, and her program
generates the plot on the area map, with area calculated for each lot.
I have not talked to her, so am not sure how she has allowed for
deliberate error of the signal which is a lot for small lots. But, if
the error is consistent, then the errors will be the same, I don't
know, in which case the area will be correct, just a locational error
of a few feet which is not important.
I'd like to meet that brilliant young woman... |
