I've had my Garmin 830 for less than 2 years, and it is beyond the warranty. I noticed that the screen started to delaminate after I rode with it in some light rain several months ago. It continued to work properly and the delamination was only on the left side and top of the screen, and was not getting any worse. Yesterday, after crossing 2 cattle guards it shut off. I stopped and tried to get it to work. Nothing I did seemed to work. I was convinced that it was dead. After riding a few more miles, and continuing to try and start it, I noticed that the screen was totally delaminated and open on the left side. I could look into the computer. I'm very disappointed after paying so much for this computer, and it breaking so easily...
