To replace the radio, first disconnect the cable from the negative battery terminal and disable the airbag system. Next, remove the center cluster trim panel, then take out the radio retaining bolts to detach the radio from the instrument panel assembly, pulling it out and disconnecting the antenna lead and electrical connector. After that, remove the left and right mounting brackets from the radio by taking out the four bolts from each bracket. For door speakers, remove the door trim panel, disconnect the electrical connector by depressing the release tab, and remove the speaker mounting screws before taking out the speaker. The installation process is the reverse of removal. For door tweeters, remove the door trim panel, disconnect the tweeter electrical connector, and remove the two tweeter mounting bolts to take out the tweeter, with installation being the reverse of removal. The optional front center speaker, located in the top of the instrument panel, requires the instrument panel to be removed before taking out the front speaker mounting bolts and the speaker itself, with installation being the reverse of removal. The optional rear luggage compartment speaker, located on the right side of the luggage compartment, necessitates extensive trim panel disassembly, starting with the removal of the tonneau cover retractor sub-assembly, tailgate weatherstrip, deck board sub-assembly, rear floor mat support plate, right deck floor box, rear deck trim cover, right upper deck trim side board, right side trim box assembly, right rear door scuff plate, right rear door opening trim weatherstrip, right deck trim side panel assembly, and right inner roof side garnish assembly. After disconnecting the speaker electrical connectors, remove the five speaker mounting bolts and the speaker, with installation being the reverse of removal. For rear tweeters, also located in the luggage compartment area at the upper ends of the O-pillars, follow a similar extensive disassembly process, starting with the tonneau cover retractor sub-assembly and continuing through the various components until reaching the tweeter, disconnecting the electrical connector and removing the two mounting bolts before reinstalling in reverse order.
