Audi helps a little by making the audio menus red, navigation menus blue, and
phone menus green, letting you quickly see which function you are using.
On our
phones there's a
green bar at the top for calls and the recent apps
menu for everything else and neither is more than a tap or swipe away, but on Wear OS navigation doesn't feel quite so simple, and a single tap — whether accidental or intentional — can leave you far from where you were before.
