I recently put in a new deck as well as new speakers. I must have done something, because there is a new yellow light shining bright in the dashboard that I've no idea what it means. It looks like an upside down light bulb with an exclamation point in the middle, surrounded by 7 dashes.

THe manual I have is all in German, and I dont sprecken sie deutsch. Any help you guys could offer would be good. thanks.
