dopoka Posted April 4, 2010 Share Posted April 4, 2010 I just upgraded my 400T to software version 3.70 and it will no longer power on with lithium batteries regardless of the battery setting. It just throws up the GARMIN splash screen and then powers off. I had this same problem with both my 60CSx and Colorado before they added support for lithium batteries. My Oregon actually had lithiums in it when I did the upgrade since I use it for climbing in the cold and had been working fine with them all winter. I know that the lithiums will probably work if I drain them a little, but I hate just wasting expensive battery power by draining them down to where they will work. Has anyone else seen this issue? Thanks Quote Link to comment
