Thanks, I have checked from time to time with the link to replies to my posts, but I missed this reply. I did use this tutorial. I am in Virginia. A can convert some quads into MP files, but with others on Demo2 it says it is unable to allocate memory. It seems related to the amount of elivation variations in a quad. I have one quad successfully converted, but only one. Thanfully it is the area I priamarily need. I have another map on my GPS, but I am trying to get more detail here. Can I go with just the elevation data in the step 9 cobining, and overlay that over my other map in the Garmin 60csx?
