Garmin GPS II plus powers on then immediately off

[sdowney717]

Each and every time.
It worked a few years ago.
I have held onto this as a backup device.
so any ideas? When it powers on you see the globe screen for about 2 seconds then it dies.

Change the batteries?

It is running off the cord with no batteries.
I will check with batteries inside.

Some cable powered units have a small 'memory' battery (button size) inside (e.g. some Raymarine). When this battery goes flat, the units behave in a way similar to what you described.

Look inside your Garmin - maybe it too has such a battery. You will likely find a replacement on the aftermarket.

How old is it?

[sdowney717]

OLD, like more than 10 years?
It is a 12 SAT GPS which can output NMEA serial to a computer.

just asked because my magellan backup did the same thing after 2000. evidently it wasnt programmed to exceed that date.... basically it was new never used except to test occasionally...
