I contacted Garmin about a year ago about my 60 cs powering up for only about a minute. They had an outside agency contact me after I tried twice. The outside agency didn't respond to my emails. I took the unit apart myself recently and the internal battery came loose of the circuit board. Taking some of the board with it. I tried solder it back but their wasn't anything for it connect to, so I epoxy it. It would last for about ten minutes after that. The unit is out a warranty so I didn't have anything to lose. I a senior SAR person and I've heard of this happening to others and Garmin fixing them if still in warranty. I'd advise anyone not to by any 60 cs out of warranty or at all if you plan on using it out in the wilderness.
