Talking to Garmin GPS receivers

Not much progress over the bank holiday weekend – I spent the weekend camping in the Brecon Beacons in Wales, attending a geocaching event. While there I enjoyed a great walk up Pen y Fan, doing several caches en route.

Now that I’ve returned, I want to use Ammotin to review the hike and help me log the caches I did. I’m busy writing code to talk to Garmin GPS receivers over USB, so that I can review my tracklog on the map to see where I’ve been. This work is progressing well with my GPSMap 60csx, but I’ll need to beg and borrow other units for more testing! I hope to have it talking natively to the most common units used for caching. For all other units and power users I’ll provide a way of using GPSBabel or other command line tools to transfer data to and from the receiver.

Thanks for the questions and other feedback via Twitter too. Keep them coming!
