Friend has a 2023 Subaru Forrester that won't allow you to do anything until the startup splash screen does its annoying thing. Left your radio on when you got out? Sorry, can't turn it down or off....yet...And if you put it in reverse...sorry, backup camera doesn't let you use the controls or knob either. Shift back to park and then wait out the startup screen to be able to turn your volume down....seriously. Why have a knob that doesn't always work? And it will start playing from the phone, not the radio. It starts to autoplay whatever you were listening to last on your iPhone. Even if the phone is quiet and you're not listening to it before starting the car, on car startup, it starts playing form your phone. It's a very bad design that doesn't seem to be getting any better, and probably worse, as time and model years move on. It is the number one complaint....why don't they fix it? It's not doing what people expect.

Thanks for the info, this was a minor annoyance, which I now understand better.

If you hold down the 'Source' button on the steering wheel for a few seconds, it will turn the radio off, and it will remain off when you restart the car.

Great info! Thanks Evan!

I don’t listen to the radio. I have my favorite cds on a flash drive playing on media. I want it to start up when I start the car.
