Mercedes-Benz S430 Problem
Average Mileage: 93,357 mi (10,000 mi - 264,000 mi)
Visitor, 2006 Mercedes-Benz S430, 60,000 mi
CD Changer went bad 1st. It stopped working and then we began to have issues with the Main Head Unit in the dash. It turned on and off intermittently and finally went out completely. We have yet to get a proper diagnosis for this issue.
Nav unit will not boot up. Mercedes dealer wants to replace the whole unit for $4500. I don't think its the unit but a computer glitch.
