2019 Forester Touring CVT
So I noticed this too and consider it either a minor bug or a poorly implemented feature. This is tied to the new key-off power feature where the infotainment stays on after you turn the car off, until you open the door (you can also roll up/down the windows). If you are using a MEDIA input via USB ports (your phone, iPod, USB stick), those USB ports lose power at key-off, and the infotainment automatically switches to the last used radio input, the same way as if you would abruptly disconnect your media when driving. It has startled me many times already. I wish it would just mute if a media input is playing at key-off.- Can't figure out why the radio comes on after starting or stopping the car (the push button start or stop).
Incidentally, has anyone else noticed that the AM volume is about 1/2 as loud as FM and SXM? Or is it just mine? If I'm listening to FM at 15, I have to turn it to 25 to listen to AM at the same volume.
