I downloaded the North Cumberland Tn OHV trails map but can't open anything it looks as if it's only TYP or img file. I want to put it on a Trail Tech Voyager and will need to be GPX file. I can convert the text file with GPSBabel but all I get is the waypoints. Any suggestions? I'm new at this. :-\
I assume this is the map? http://www.gpsfiledepot.com/maps/view/446/
That map is in Garmin's proprietary vector format (.img file). The .typ file is like a style sheet that specifices the appearance of the lines and points on the screen. So it is intended to be used on devices made by Garmin and your Voyager is not compatible. In the past it has always been the policy of this site not to discuss ways to convert or modify the work of another map author.
If you want to convert this map to another format, the best approach would be to contact the author. If willing, he should be able to send you the source data that he used so that you can make your own map. http://forums.gpsfiledepot.com/index.php?action=profile;u=86
