New to the evo and android software so don't laugh. I go to use the nav today and it says there is an update. So I click the button and see it is updating after it is done I use the app. Log out go back in and it says update available. Well long story short I do this 4 times until I realize that it downloaded the update but I HAVE to manually install it from my sd card. I felt foolish. Anyways my version is 18.104.22.1682. I did not check the version number before and I do not know what this upgrade did. I just install new updates when I see them.
