How to Replace a Mercedes C230 Radio

1. Disconnect the cable from the negative battery terminal. Loosen the nut on the cable clamp until the clamp can be slid off the terminal.
2. Slide a DIN tool into each of the openings (there are two) on the face of the radio until they click and lock into place.
3. Pull the DIN tools out away from the dash and the radio will come out with it.
4. Disconnect the antenna and electrical connections from the back of the radio.
5. Plug the antenna and electrical connections into the new radio and install into the dash. Installation is the reverse of removal.
6. Reconnect the cable to the negative battery terminal.
