Nope, no water, no excessive heat, no drops preceding the failure, right kind of batteries.

I wish there had been something that happened that I could point to and say - "That's why it happened."

I don't intend to badmouth Garmin, I've had 3 or 4 of their units over the past 20 years and never had a problem. But I do think that 6 years is the longest I've kept one - I usually sell the old ones when I upgrade.

Oh well - time to shop for another on - unfortunately it looks like the 60CSx has been discontinued so I am going to have to wade through their product line and see what's comparable.
