To uninstall the radio, first depress and sepaate the negative leads for safety from the battery negative terminal. Next, take out the dashboard center bezel and unscrew the radio mounting screws, then, take out the radio that is installed in the instrument panel, freeing it from the clips, electrical connectors as well as the ground wire. Again, it is recommended that the antenna lead should be disconnected slowly before the removal of the radio and for installation is the same process as removal but in reverse. For door speakers unscrew the door trim panel followed by unscrewing the speaker, pulling it out, unplugging its electrical connector, and removing the speaker from the vehicle, while to install it you reverse the process. In the case of instrument panel speakers the over head has to be removed then the speaker has to be unscrewed and pulled up, the electrical connectors have to be released and the speakers pulled out, the processes are similar to that followed when putting the speakers back into place. For rear shelf speakers, you have to uninstall the whole rear seat, then you have to pull of the pillar trim panel, you have to pry out the seat belt trim bezel and finally pull of the rear parcel shelf trim panel. Remove the screws of the speaker and during the installation of the wires, make sure that the wire connectors are towards the middle of the car.
