I too had a chirp that was programmed with a Garmin device I no longer own. So I downloaded SimulANT+ and figured out how to clear the chirp. I had to buy a USB ANT stick for about $49 bucks. I know the chirps are less than that but I like the challenge to see if it could be done! YES, I now have a chirp that I can re-use!!! :)
Cache-ON....
I don't know if the chirp is actually outdated, just another way of setting up your cache... I like anything electronic... more toys to play with!!!
