OK folks,
I thought it was clear that I had both ; V5.0 Mapsource AND V5.0 mapping.
To get the latest Mapsource program, go to the Garmin website and look under "Software updates", scroll down the list and you'll see "Mapsource" in amongst all the varoius gps units listed.
The file I posted does have extra waypoints. These were for the route that I had planned to ride. However, when I reached the top of the hill, I found the track that I wanted was blocked by a barrier. I rode down to the D48. Turned round and went back to the top. (The track to the D48 is mostly tarmac) Then went down to the D336.
The first track from WP "TRACK NORTH" is fairly easy and well used. The track from the top to D350 is harder and rougher but is just looser on the surface. I overtook an horse box going down that one!!
I'm sure that there are loads of dirt roads to do in that area. I only had one day because my trip was a long weekend. The off road excersion was to be included in the days ride in the file below.
Have fun. I did.
