How to Remove the Factory Stereo From a Mercedes Benz CLK 430

1. Insert a large flat-head screw driver between the head unit and the dash. Pull back slowly on the screwdriver, prying off the dash in the process. Be cautious and do not rush; the plastic in older models may be brittle.
2. Unscrew the head unit. The existing stereo will be attached with two screws. This is standard in all cars. Use a wrench or screwdriver to unscrew the head unit from its fastenings, as some models have screws and others have bolts. Once the screws are removed, the stereo can be pulled out.
3. Disconnect any wires from the back of the head unit. The antenna wire is a single larger wire; it can just be pulled out of the deck. Unhook any other wires. The stereo is now removed.
4. Install a new stereo by reversing the process.
