I went swimming with my Garmin 735XT today, and when I got out, it started buzzing continuously.
Then it started cycling through these diagnostic screens at a super-fast rate.
Then it started showing a single orange square pixel.
I tried to power off, and it kept doing it. Did a hard reset (holding power button for 15 seconds), now it just buzzes continuously, cycles between a charging screen and a Garmin logo. Doesn't allow me to do anything, and computer doesn't recognize it.
Really hacked ... have 2 huge races coming up in next 10 days and I'm without my watch.
