David L. Johnson said:Santa brought me a Garmin 205 roadrunner for the winter holiday
celebration, but I don't think this is what I need. It is primarily a
training device. What I need is to be able to figure out where I am, and
how to get where I need to go. I need maps and route planning, not lap
times and max speed (this I can get with a computer).
I've been using my Garmin eMap for the last 7 years. In addition to
the maps and routes, it also gives me the usual bike computer functions
like speed, average speed, max. speed, elapsed moving and total time,
etc. But the eMap model has been obsolete for the last few years.
Among today's models I'd consider the eTrex VentureCx or the 60CSx
depending on how much you may want to spend. Both are far superior to
my eMap. In addition I strongly recommend you get the Garmin map
software (CityNavigator-NA for the US and Canada) and a decent size
micro-SD memory card.
Both models will give you a color map display with detailed maps (as
long as you have the CityNav software) and will let you search for
street addresses, many business locations (handy to find grocery stores
and restaurants when getting hungry while touring), other
points-of-interest, and will show you the fastest and/or shortest route
to get to them. The 60CSx costs more but has a more sensitive receiver
chip (less chance of losing the satellite signals under especially
dense foliage cover) and also includes a pressure sensor for better
altitude data under marginal reception conditions. It also has
displays of the elevation profile and data on cumulative gain that are
lacking on models without the pressure sensor although you can get the
profile and similar data later when hooked up to a PC.
Quoted message said:Oh, one last thing. I only use linux, so windows-only pc interfaces are
not favored.
At the moment, the Garmin map software only works on Windows machines
(Mac support has been promised but the date is uncertain). However, if
you get either of the above units along with a good-sized microSD card
you should only need access to a Windows machine for a one-time load of
all the map segments you need. So find a friend with a PC who'll let
you do the map upload and you won't need to touch Windows again - at
least for a year or two (or more) when you may want to get updated
maps.
For getting the tracklog/route/waypoint data in and out of the GPS
there are a variety of software products that support linux and other
OSs in addition to windows.
