Use same symbols as GPS send (File=>Export=>GPX)
When generating the GPX files you can have GSAK generate the <sym> element as being the same as what you have set up when you send waypoints to your GPSr. This enables other programs that read GPX files to recognize the symbols you have used rather than just the default Geocache and Geocache Found. For example, the new Garmin MapSource 6.5 now reads GPX files and reads the <sym> element to display that symbol on the map.
