Find someone to let you borrow their main battery to see if that is the problem first. My main battery failed and the unit would not even recognize it. ACS has them for $43.95.

Thanks Tommy, I called Garmin today they say when it shows (battery missing) after a charge the LI ION needs to be replaced. Have a good day no flying here it was -2 last night.

Here is a web site with instructions and pictures on how to change the internal battery. I have not had to do mine yet.

If you do it let us know how it works out.
