My Z82 worked for a couple weeks then last night was not targeting well. Everything was >100yards too long or just wrong. I plugged it into Garmin Connect tonight to see if there were software or updates to help and now it's stuck in a boot up loop. The Garmin Logo screen to the maps loading screen to the green progress bar, but then back to the Garmin logo screen. Repeats. I can't even seem to turn it off. Seems like the only way I can stop it is by plugging it back into my computer. From there I have tried diagnostics mode but nothing there was a hard reboot or useful to my problem.
I emailed support. likely 3 days. Tried the chat, there was 1 person in the queue but my wait time just kept going up from 2 minutes to 15.
Software Version 4.40
