    It’s because they don’t want the car battery running flat during installation. Kind of like how your phone requires a minimum battery charge to update

      Yeah but shouldn’t the power usage for the infotainment system be similar to a cell phone at this point with similar hardware where it really shouldn’t be possible to run a car battery dead during an update?

        Ideally. Depends on the update time too. I know flashing ECU tunes requires a battery topper. I’ve also killed a car battery modding my infotainments firmware so it’s totally possible. But most likely Subaru is doing it out of an abundance of caution… Don’t want an angry customer coming saying the update killed their battery
