You may also want to play around with customizing the color and or pattern of the snowmobile trails to make them stand out. You would probably want to make what is known as a 'transparent' map to overlay on top of topographic or street maps already on your unit. To make a MapSource map from a shapefile you will need to follow the instruction at this link: Custom Maps. This utility is rather straight forward and will convert shapefiles into GPX, GBD, KML and many other formats. To convert any shapefile into a GPX file there is a free utility called DNRGarmin. To my knowledge and experience these are very different tasks. GPX' and in the body of your post you want to know how to convert the shapefile into a garmin map.

If anyone can lend a hand or some advise, would be greatly question is a little confusing.

I have a 1 gig memory card for my unit, so if I can get this shape file converted to a Garmin format, the size should not be an issue. Has anyone done this? I can send you the 8 meg shape file if that helps.

I'm a little nervous downloading trial s/w if needed to do the conversion, and for a one time conversion, not worth purchasing it to find it doesn't work. I have done some reading on this at this site, but it makes no sense to me. Both of these units will accept shape files.

The originator of this file uses two or three different types of GPS receivers.Ī couple are high end ($6000 units) manufactured by Trimble, the other is a cheapy ($300 Canadian Tire version) made by Garmin, model 12. I have a Garmin GPS 60 CSx, and would like to be able to load these trails into my 60CSx the same as any other Garmin map set so I can see the snowmobile trails on a map of the province. Not file (.shp) with all the Snowmobile trails for New Brunswick which is approximately 8 meg.
