I just got a 2011 Brabus with a Highline Radio. After a month away, I came back to a dead battery. New battery is now installed, but I can’t get the panel to stay closed on the radio/navigation system. Silly me, I had inserted a CD, which won’t play, and won’t eject, and the entire panel won’t retract to the right position. I can gently push it back into position, but it will not stay there. Looking for some troubleshooting genius to resolve this headache! I basically can’t operate the radio or navigation because the screen is now horizontal (flat), not upright and in place as it should be. Thanks for any suggestions!
