I posted because i wondered if anyone else had a problem with that cache. I also noticed that description has a photo in it and wondered if that could be causing the unit to reset. I found update on the Colorado page but don't know about the firmware. I will try that this morning.
Happy hunting!
There is definitely a known bug where some cache descriptions cause the Colorado problems. If you can repeat it with the same cache description every time, then I'd say you're hitting this bug. Which software version are you using? I would update to version 2.3 (which, I think still doesn't get picked up by the web updater, so you have to find the link to the update.) I'd also update to version 2.6 of the GPS chip firmware (the web updater will install that for you).
