So I got a reply. This is my answer to the reply. Reply below this. Original request for warranty service below their reply...
I don't mean to sound rude but you're way off base. I was using the Xero. I started to create a new session and it turned off. I turned it on, it came on for 1 second or less, then turned off. I tried to turn it on 6 or 7 times and I got the same result. I thought the charge might be low so I plugged it in. It turned on and it started charging. When it reached full charge I pressed the power button. Nothing happened. It stayed on. I couldn't turn it off. The power button NO LONGER WORKS. I can't change menus. I can't reset. I can't download. I can't start a new session. I can't look at past sessions. That is why it needs to come back for repair. There are a lot of people on a couple of shooting forums that want to know how Garmin handles warranty work. To be fair I probably didn't supply enough info but this reads like "Hey, I smashed my car into a wall and now my engine is smoking and it won't start. Tech support: Oh… have you tried the headlights and windshield wipers?"
It's broken. The primary function button doesn't do anything.
