I was looking at the article entitled, "Generating Custom Garmin GPS Maps"
http://www.gpsinformation.org/adamnewha ... mapper.htm Has anybody here tried this? Could I do something like this with a Garmin StreetPilot 2730

Sort of.

I've made custom maps that I can upload to my 60Cx but I haven't produced the basic map as described in that article. I've imported tracklogs and converted them to roads and creating a transparent overlay map that shows my tracklogs over my Topo (or Metroguide) maps.

The principle is the same and I use MapEdit to create/draw the map, cGPSmapper to create the Garmin-compatible IMG file and then MapsetToolkit to install the IMG file in MapSource. Then I can combine my "tracklog map" with Topo and Metroguide and upload the gmapsupp.img file to my GPS.

It works and the necessary programs are free.

I found this site this evening and it has snowmobile trails. I did successfully download this to Mapsource, but when I download the maps to my Garmin StreetPilot 2730 they don't show up. I suspect that the 2730 isn't configured to accept this like handheld GPS units are.

I checked the Garmin website and your 2730 can have additional maps uploaded to it.

I haven't tried the actual maps on GPSsledmaps but I use their tracklog files and convert them to maps which do upload to a 60Cx and a zumo.

Did you first install the sledmap in Mapsource or did you use Sendmap to go direct to the GPS?

I used Mapsource.

When you used "Send to Device" in Mapsource, did it appear to run correctly - i.e. no errors reported in Mapsource or on the GPS?

If no errors, then do the new maps show up in the GPS Map / Setup / Info screen?

There are transparent and non-transparent maps at GPSsledmaps. If you used a non-transparent map you will probably need to turn off all the Garmin maps, including the Basemap. A transparent map will be visible over the Garmin map. You may need to be at a particular zoom level to see the new map.

If it still doesn't work, and you want to troubleshoot it, post a few more details.

The maps work on my Zumo. I had to turn the City Navigator maps off for them to show up when zoomed in.
