Z82 stuck in boot up loop

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

It sounds like you're having a frustrating time with your Garmin Z82! Since you've already tried diagnostics mode and a hard reboot without success, here are a few more steps you can try:

Update Firmware: Ensure your Garmin Z82 has the latest firmware update. You can do this using Garmin Express.

Reset to Factory Settings: Sometimes a factory reset can resolve boot loop issues. Be aware that this will erase all data on the device, so back up any important information first.

Check for Corrupted Data: If possible, try connecting the device to Garmin Express and see if it can detect and fix any corrupted data.
