So, I think my Garmin Forerunner 50 has outlived it's relatively short life span (about a year). I hear this is an especially problematic model or as others online have described it (a total piece of $h!t). However most people say very positive things about their Garmins so I'm willing to try again.

The deal is that I run and bike so I want one I can use for both. I use a heart rate monitor too so this leads me to look at the Forerunner 405 or 405 CX depending on if I can use the Garmin Heart Rate Monitor strap I already have on a new watch??? I hate to pay an extra $50 for the CX if I can just use the HRM I already have and possibly the foot pod too for indoor running. The HRM I have looks exactly like what Garmin sells online to add to existing watches so that makes me think it would work. Since my Forerunner 50 isn't that old this also makes me think it would work. I've emailed Garmin to see if there is any warranty or repairs that can be made to the watch I have but I seriously doubt it. I am guessing this is why Costco was selling them for $99 dollars.

Any suggestions on a replacement or do any of you know if I can use the old HRM on a new model? I know many of you probably use these run/bike devices and have a lot more experience with them than I do.

I guess I should clarify that my old model didn't do the bike stuff but I'd like to get one that will even if I have to buy the cadence attachment separately.

Please help!
