Newbie here. Does anyone know what the 2 icons at the top center of the nav screen mean? Houses with numbers that change as you drive. Can't find any reference in the manual.

I believe it's just showing which side of the street has even or odd numbered addresses.  Not sure if it actually corresponds with real addresses in the area.

That actually makes sense. Thanks... I think you are correct.

It does match up to the actual house numbers, but they do seem to be not perfectly exact as you go by them. I forget if you are past them or ahead of them as they are listed.
