For the MB Companion App, coming sometime this fall, users will initially have to own a Mercedes C- or S-Class car, although support for more models is promised to come at a later date.
The main feature will be easy transitions between walking and driving directions. Selecting a destination on the Watch will first provide walking directions to the car, then pass guidance to Mercedes’ COMAND Online system once the vehicle is started. Parking will switch the Watch back to walking mode.
Other planned features include the ability to check odometer readings, fuel level, available range, and a vehicle’s maintenance code.
