How to load a partial map segment

[KnuckleDragger]

I am using an old garmin gpsIII plus that only has 1.4meg of memory. I want to load some topo info from the NewEnglandtopo map that I downloaded here but the map section I need is 3.68meg. Is there a way to crop the map since I only need a small portion of it?

No.  You might contact the map author about making you a special quad.
With that small amount of memory what you can do is going to be very limited.

wow, I dont' know of very many segments that are that small; I'm actually increasing size in my new maps.

knuckleDragger,

  I am new to this site, but noticed that one of tutorials show you how to import img file into mapsource. http://www.gpsfiledepot.com/tutorials/how-to-load-.img-files-into-mapsource-with-mapsettoolkit/. After you import the img file into mapsource, you can select  the area you are looking for and then exported to your GPSr.

hope it helps.

Thanks for the replies.

I have tried following the steps in the tutorials on this site and here http://home.roadrunner.com/~creek/garmin.htm.
I can create a small map of the area I want but I cant get it into mapsource. The first time I tried it the map loaded into mapsource fine but I couldn't select it with the map tool. On subsequent attempts it loads into the list of maps but if I select it in the dropdown box I get an error and then mapsource terminates. Not sure what I did different with those two tries or where I am going wrong.

Ideas would be appreciated.

Thanks

You could use this tutorial (a bit more specific than the one you linked to above) and just do it on a small scale: http://www.gpsfiledepot.com/tutorials/how-to-create-garmin-topo-maps/
