Thank you for that information.
This is more then likely a bad battery. If you try a new one maybe from a different source you should be able to see that message disappear.
The circuit that monitors the battery is also in the battery itself.
But if your battery lasted a while then appeared, you would have a problem inside the Garmin.
But almost always with these it is in fact a bad or defective battery.
And also make sure your charger works. In other words, if the unit just stays on normally with the warning, then its just a bad sensor in the Garmin. But...if it shuts down at all then you need a new battery.
I hope that helps?
Please let me know.
Also if you need a good place to have it serviced.
In any case, I will stick with you until this is complete.
