Battery icon on display monitor

[Steve Pickard]

Does anyone know what the battery icon on the display monitor refers to. It comes up on the top of the screen while both radio and map functions are displayed. It is to the right of the nav. Mute icon. I suppose that it is the car battery. But I am hoping that it refers to the fob battery. Thanks

The only battery icon that I have seen on my nav screen was for the battery level of my phone.

Oh, did not think of that being the case. Makes sense. So thank you.
