I've been using my 305 with great satisfaction for almost two years (the cadence sensor quit several months ago, but that's a different story). So after Friday's ride I downloaded the data to my computer, charged it fully, and put it back on the bike.
Yesterday AM I set out on a long ride, but the Garmin wouldn't turn on! Hasn't turned on since, and when hooked up to the charger there's no screen display of any kind. It's suddenly and without warning dead as a doornail.
What's to be done, if anything? It's surely out of warranty, and I can't contact Garmin by phone until Monday AM.
