that depends, were they lithium batteries, If you read a few more of the threads you will find that this seems to be a known problem with Lithium batteries.
Nope, using alkaline batteries, several sets, even used my power cable for the car, had one for my 60CS, still nothing, I had Garmin on the phone, he had me try several things, finally he said, the unit was just a dud, , but on the lithium, I use them in my 60CS with no problem, are they going to be a problem with the 60CSx???
