Quoted message said:I'm looking to get a GPS with map display for my bike,
to mount on the handlebars. This would be a unit that
lets you download maps from the Internet onto via USB
connection. Garmin Etrex has an 8 MB and a 24 MB model,
the latter more expensive with altimeter and barometer,
which I don't really need (though the altimeter would
be cute).
Anybody have any recommendations on these models? Is the 8
MB limit confining in terms of the fraction of the Earth's
surface area it can hold a map for? 😉 This is for day
rides, rather than a cross the USA trip. I'm told the 8 MB
has better screen resolution than the 24 MB.
Geez,
You seem to have brought out the luddite crowd. A quick
search of the group archives will show that I have in fact
recommended that one do primary reliance on paper maps and
non-electronic navigation aids. That said, I have a GPS and
use it extensively while cycling. I use it as and adjunct
navigation tool, a database of information, a recorder of
trips, and other things.
As others have pointed out, one of the beauties of the
GPS's you will want to consider is they are waterproof, and
easy to use in situations where paper maps are problematic.
Two years ago we were caught in a horrendous storm in
Italy, in an area where roads were poorly signed, and with
my friend getting
ill. We needed to get to town, fast, and the maze of
umarked roads was a problem. We ducked under an
awning, consulted the paper map to find the shortest
route to the nearest town, and figured out the
landmarks and made sure we could follow the same on
the GPS. Tucked the map safely away in waterproof bag
and followed our electronic 'nose' into town without a
hitch. Many times recently we have done the same -
easy to use and follow in conditions where paper maps
will become oatmeal in your hands.
And do not listen to those who think you should rely on
'ppl'. 'ppl' may not be friendly, may not speak the same
language, and often are nowhere in sight when you need them.
I was lost once in the Amazon basin, probably 50-60 km from
the nearest 'town'; if I waited to ask 'ppl' where go I
would still be there - but probably not alive. And with
canopies going hundreds of feet above you, and just occasion
'trails' through the jungle regular navigation aids were not
much help. If I had a GPS I would have gotten out faster; as
it was I had to navigate by sound - using aural cues to
locate the main river in the area then follow it upstream to
a 'village'. 'ppl', visual cues, etc. were useless.
Another use of the GPS is finding things. I use a download
map set that has data about the areas, including
location/address/phone number of hotels, restaurants, car
rental agencies, train stations, stores, etc. We used that
once, again in Italy, to locate a train station when caught
in an electrical storm. We used it just yesterday to locate
a place for dinner.
As far as a GPS unit, you want a couple of things. 1) you
want to be able to download maps, routes, data, and upload
tracks. To do this you need an interface that can be
connected to a computer, and lots of memory. Forget the
idea of 'download maps from the Internet'. The two major
GPS companies have proprietary formats and to really get
an extensive map set you need to buy theirs. Figure that
into the cost.
2) You want one that is rugged. My eTrex Legend survived
my (hit and run) accident that left me unconscious with
three missing teeth, two broken arms, and a lot less
skin. There is a piece of the case that got 'sanded'
down by the road, but has not missed a beat in the two
years since the accident. 3) You want one that is
waterproof. 4) you want one that is relatively small.
4) you want one that gets good reception. Finally, be
willing to compromise. The units with the most memory
are either relatively large and/or not all that suited
to downloaded maps and/or not all that
rugged/waterproof. I thought of moving to the Garmin
GPSMAP 60CS recently; lots more memory, color,
supposedly better reception; but it is much larger than
the eTrex Legend/Vista, and I cannot live with
something that big on my bars.
Good luck,
