I just got a 2017 Citadel V8. Really like how it drives. But one major annoyance I noticed is the radio. There is no way to turn it off! It can only be muted with what normally would be the power button. Then the next time I turn on the engine, the radio comes right back and starts playing. What's worse is that it doesn't go back to the last radio station or media played. Instead, it randomly picks a media/channel/station, which is often invalid. So it blasts static as soon as I turn on the engine, unless I mute it or change the station. Has anyone experienced this? How do I make it default to the last band/station played?
