Has anyone else had problems with the cadence sensor for the Garmin 305? Garmin just replaced mine for the 2nd time. The first one started draining batteries overnight (sitting in the garage). The second one simply stopped working. I tried all the resets that the tech recommended and they finally replaced it also. Is this a common problem? If this one dies I'm just going to give up in frustration.
I might add that Garmin has been very good about replacing them, although their response time for support inquiries is a bit slow.
