For those with big runners that run the Garmin Astro GPS system, there are software updates available.
I called with a question because one of the blue charging LED's is burnt out. One still is operative, and I can tell when the unit is on charge, so I'll just leave it for now. The tech offered to walk me through the software updates to both the 220 gps unit and the dc-30 collar. I was way behind the times, and numerous updates had been available before the most current ones.
In any case, both units are now current with the latest updates, and the latest info for the chipset..
I'm expecting even better performance from an already fabulously performing tool!
