@robby denning, at least it is happening before you left. This year i went to Colorado, I set up camp and sent messages out that camp was setup and everything was good and went to bed. The next morning I went into to town to get things and got a text from my Dad as to why I haven't let them know how things were. I tried some more messages in the Walmart parking lot and nothing was going through.
Tried some things on my own and finally called Garmin. I ended up having to do a soft reset on the unit to get it to work, which required a WiFi or mobile data connection. This took from 9 AM to 3 PM. I used it that night and everything worked. I tried it the next morning, left it on all night, and got no response. After waiting an hour I drove to where I got reception and called my Dad to see if he had received the messages, which he didn't. So I ended up pulling out and coming home because I couldn't depend on it to work. So I drove a total of 4 days (round trip) for a 2 day camping trip.
I called when I got home and they sent me a replacement, refurbished, unit which I got on Wednesday. I tried to activated it today and couldn't. Called Garmin, minimum of an hour wait on hold, I left a call back number and received a call back 45 minutes later. It turns out the Dumb ass

that returned this unit never bothered to deactivate it from their account. Garmin is looking into it but won't know until next week as to how to resolve this issue.
