And one more question I have. Is Basecamp and Mapsource the same type of program. What you'd use to transfer data from computer to gps? One thing I did was get rid of Basecamp and load everything into Mapsource. Then too I realized I had to be careful or somethings are limited as to how many you can load... Such as tracks. I can only load twenty at a time. Martin has quite a few. The first time I loaded the first twenty on the list thinking I'd get em all. Then I had to manually delete each one. It's time consuming as you learn about these things.
