TSD, if you want Topo Maps, not in 3D, your 60CSx works fine. I have a 60CSx and a eTrex Venture HC, both have Topo maps loaded and my 60CSx has roadmaps. I am quit comfortable not having 3D Topos. One thing I have learned is that the 60CSx will only hold 2000 map files, Street, Topo or a combination. I just have multiple micro SD cards, only $10 a piece for 1GB to have the entire US. I also use Garmin's POI Loader to increase my waypoint numbers because my waypoints are now points of interest. The downside to the POI Loader is similar to what Turtle3863 mentioned, you can't delete the custom POI's on the trail. You can only delete all them and reload. The Colorado looks interesting but you could buy a cheap laptop and 60CSx for the same price.
How do you get the full use of a card? I have a 2GB card but I can only load so many maps at a time, city select and TOPO. When I prepare a second set of maps and load them it erases the first set i loaded, I can't get over, as I recall, about 680 MB on the card. Whats the secret to adding more maps without erasing the first ones?
You are correct, my card is less than 1GB of map memory used. The limitation is the quantity of maps you install which is approx 2000. Example; I have most of the eastern US roadmaps and topo on a single card. The number of maps installed is 2008 but the memory usage 918.9 MB so the rest of the memory is unusable except for Custom POI's which use about 1k per Custom POI. Custom POI's import from a pocket querie GPX file and the software is free from Garmin. My estimation is that I can load about 80,000 Custom POI's into my 60CSx. The 2 downsides are you can't delete Custom POI's on the trail and they slow down the screen updates a little bit but nothing drastic based on my experience (I only load about 2000) at a time. I have never loaded my estimated 80K. Captin BB I recommend if you have a different use for your 2GB MicroSD then move that to your camera or MP3 player and purchase a 1GB for your 60CSx. Here in Cincy Micro Center has 1GB MicroSD's for about $10.
If anyone has any questions email me and I will be more then glad to help.
Turtle3863, sorry about the thread jack.
