It couldn't be easier to disable auto start/stop on your 2023 Subaru Legacy. This intelligent device restores your preference for auto start-stop automatically which eliminates the need to manually disable auto start/stop via the touchscreen with each ignition cycle.
While our Autostop Eliminator connects to the stereo camera on the EyeSight system, we do not hack the vehicle to make our device work. The stereo camera only serves as a location to connect the Autostop Eliminator to the vehicle network. The video below is based on the Outback, but the installation is identical with the Legacy.
The device simply plugs into the overhead stereo camera on your 2023 Subaru Legacy in the same way it's shown in the Subaru Outback video below.
