Technology Sucks

After perusing some forums I decided to try a hard reset on the Edge 305 hoping it would make the random shutoff problem go away. It hasn't. It was really good on Saturday being on for 5 hours but last night it shutoff after only 45 minutes. I did call Garmin and they were really good about issuing an RMA, but with LOTOJA in one week now isn't the time I want to be without it for two weeks while they fix it. I think I'm going to try deleting the history from the device and the courses I've install and see how that does. And then send it in after the race.
