On the main screen you will see a settings box. It's in the list of options.

I mean, do you have to pay for an update (how much?), and is it a memory card upgrade or via the Internet somehow?

I have the old 1690 in the Suzuki dock. I can update from Garmin for $49 each time, although I don't. If the Android head unit has a cheaper update path, I'd probably be more inclined to install.
