I'm not sure what year Outback you have, but on a 2024 Premium, the Starlink system can set many features via voice command, not just audio. Climate control, cell phone including some apps, navigation if so equipped, etc. The system is a bit finicky when issuing commands in that you must use the correct phrase when issuing the command. Most newer models should have similar capabilities. The Starlink owners' manual lists all the commands. If you need a copy of the manual, it is available on the Subaru website under "Vehicle Resources" on the "Owners" drop-down. You input your VIN number or your year, model and trim and it will post links to all the manuals for your car.
