Garmin 530 has been solid-as-a-rock for me, and it updated to 8.0 while USB connected last night...
Computer started the ride this morning just fine (HRM dual strap, eTap, and 2-lights connected to it), and then power-ed off after ~15 miles... I turned it back on and continued just fine... About 10 miles later it crashed hard and lost all ride data...
Ugh... 8.0 not a good thing for me so far...
Digging into downgrade/other options...
