My unit has gone completely bonkers (frozen) and will not respond to all measures. It is stuck in the blue triangle screen. How do I locate serial number to initiate support from Garmin (it's required)? Thanks in advance.
I was doing open water, and start & stop button was not working. So I tried everything including this https://support.garmin.com/en-US/?faq=LePCURziXd4A5qZLwqKEwA&productID=641435&searchQuery=Frozen&tab=topics
No joy! Ugh...
