Hmmmm, I'm still up in the air about which one to get. Size wise, how big is the 60CsX? Also, can you do mapping with the Forerunner 205? I really like the size of the Forerunner 205 the more I look at it. I would like to start putting together a database of maps in Michigan of the local trails that would be downloadable from my website. Also, is there some sort of recognized file format for GPS maps? Could I have a list of maps on my website of GPS maps that people could download from my website and upload them to their own GPS? Could I use the Forerunner to create these maps? Could I also create printable maps, ie. If someone from out of town comes to Michigan, can I just print them up a map I created with the Forerunner? I guess that I think that the GPS 60CSX might be too big to mount on my handlebar. Has anyone done this? Do you have pics of it mounted?
For dimensions and picture of relative size of eTrex versus the 60Csx, see
this thread.
See more about the features of different GPS units and relative value on same thread link. In particular, the wrist mounted units, Foretrex and Forerunner, don't have altimeter or compass. And the Forerunner can't store routes, a critical flaw for navigating. The Foretrex is better and stores routes, but costs more than the eTrex units without a compass or barometer. But either of these units can store tracks and can be used for making maps of the local trails as you desire.
There's become a universal format, gpx, for waypoints, routes, and tracks. A few web sites (like geoladders, topofusion, and Motion Based?) are allowing people to download gpx files. But unfortuantely, there's no good national data base yet, and very few bike routes. I sometimes beg routes from local friends with a GPS. On new routes, I usually still have to figure out waypoints and routes out myself from matching a topo map of the trails I find on the web to Garmin's Topo on my computer screen, and putting points using altitude and landmarks like streams and mountains.
But all the different computer maps are all proprietary format. The only maps that can be downloaded to a Garmin GPS are Garmin MapSource maps, such as the Street maps and Topo maps.
For making maps, look at the excellent book "GPS Mapping: Make your own maps" by Rich Owings, who logs onto MTBR as Redwoods Mtn Biker. See his web site
here. The book just came out and gives a lot of information on how to handle GPS data and work properly with the newer web based programs as well. Well worth the purchase.
