One day the radio stops working. Can not change station, nor adjust the volume. Can not even turn off the radio. Once got home, stop and restart the engine. For whatever reason I can make adjustment with the radio. Several days or weeks later the GPS froze. Can not switch to radio or any feature. Again once got home. Stop and restarted the engine. GPS works fine. Able to access the radio. Several days or weeks later. The Bluetooth for the phone stops working. Can not make any adjustment to the radio. Again, issue goes away once the car is stop and restarted. So far the issue(s) have not reoccur. Is Subaru using Windows to run the radio, GPS, and Bluetooth?
