my 60 CS performs quite well, if I can get decent reception. poor signals sometimes in remote areas.
garmin engineers claim Nuvi models (except 200 & 600) have chips equal in performance to 60 CSX's.
another advantage of Nuvi is pre-loaded mapset of entire US. had to purchase mapset separately for my 60 CS.
it's $60 for map updates ... no matter which way you go. GPS info comes from US funded GPS satellites. have always burned my hide.... this info costs so much, when Garmin gets it for free.
Ehhhhhh I had one of those nuvi pos I bought
it because I was pulling a 53' trailer to Maine
the sob kept telling me to turn in stupid places
for truck trailer combos and put me in a dead end
having to back into someones yard to turn around!
Then it tried to route us through the friggin bronx
so we had to go town to town to make it do what
wanted it was a pain so I gave it back. I had never
been to the NE and wanted to know lane changes
before I got to them so I did not have to get over
in traffic. It did do that one town to the next but
I always had to second guess it's motives and
kept wondering why the heck it was trying to
take me a :censored: route in truck and bus mode.
If I were in my car I would have went the Jersey
turnpike to see the big mess but really I am never
impressed with large cities just too many personalities
with way too much agendas.
