With most of North America extending DST by three weeks you might have noticed that the clock on your Forerunner is wrong. Garmin has already released a DST bug fix for the 205/305 but not for the older 201/301. They suggest setting the DST settings manually. Here is a short video showing how to manually change your DST settings on a Forerunner. When Garmin releases an update I'll post it here.

I still don't understand why these updates were so slow to be released by Garmin. The change to the DST rules has been public for a couple of years now.
