GPS Track
I didn't see this anywhere on the forum. It's a simple app. Took a little while to get it installed on my pearl, but then it was easy to connect to the bluetooth GPS. Allows for track logs to be exported to SD Card as .kml, .gpx, or .csv files. Shows basic trip info, distance, average speed, average elevation.
Took a nice 5 mile run this afternoon with the puck in one jacket pocket and the pearl in the other, and I watched a flyover of my route on Google earth about 3 minutes after I got home.
I haven't tried using a kml file, but the gpx files work great. Simply export the track log as a .gpx file, open google earth, then open the gpx file.
