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,
