How do I remove and reinstall the radio and speakers in a Mercury Mariner?

For 2007 and earlier models, disconnect the negative battery cable. Remove the radio by using special tools or bent coat hanger wire. Insert the tools into the holes at the corners of the radio assembly to release the retaining clips and pull out the radio. Disconnect the antenna and electrical connector, then remove the radio. Reinstall in reverse, ensuring the retaining clip snaps into place. After reconnecting the battery, the PCM needs to relearn its idle and fuel trim strategy. For 2008 and later models, remove the center middle instrument panel trim panel. Remove the audio unit mounting screws and separate the unit from the trim panel. Disconnect the antenna and other wiring if there's a navigation system. Side brackets can be removed if needed. Reinstall in reverse. Note that a new radio must be programmed by a dealer service department. For speakers, remove the door trim panel and speaker mounting screws for front door speakers. Remove the door trim panel for rear door speakers. Access the rear subwoofer speaker by removing various trim panels. Disconnect the wiring, remove the mounting bolts, and take out the speaker assembly. Installation follows the reverse order.
