I have a 2014 mini cooper roadster with a Harmon Kardon sound system that sounded really good. After less than a year and a half, the amp died. Long story short, after many attempts, the sound system is now terrible. Terrible! And you can't go after market because the entire diagnostic system for the car goes through the amp and the radio. So, I'm stuck. And they've told there's nothing they can do. The door locks don't work either, they never fixed them. The trunk opening is hit and miss, but they say it's fine. They're beyond awful. You're wasting your money and buying nothing but a lot of headaches.
