Query: Power on problem

I've had the 305 for 11 1/2 months now with no issues, and now it fails to power on. Up until now it has worked nearly flawlessly. This unit was not abused, dropped, emersed in water or put through anything negligent. Just normal usage - 75 to 100 miles a week - mostly dry rides. I was very happy with the unit - it has all the features that I need for basic cycling without the 705 bells and whistles. I've tried the FAQ's at the Garmin site and the unit does respond (reset + mode) - but only with it hooked up to a computer via a USB cable. Without the cable, nothing! I searched the web and it turns out the power on issue is a common problem (among other problems). I will attempt to contact customer support to see if they'll fix or replace this unit, otherwise, beware before purchasing the Edge 305!
