Q: How do you remove and install the radio and speakers on Toyota Prius?
A: Disconnect the cable from the negative terminal of the auxiliary 12-volt battery, ensuring to perform the initialization procedure upon reconnection. For 2001 through 2003 models, use a screwdriver wrapped with tape to pry off the panel below the heater controls, then pry out the hazard-warning switch and disconnect its electrical connector. Remove the fasteners at the bottom of the center panel and beneath the hazard-warning switch, pry the center panel out, disconnect the wiring, and remove the radio from the center panel, with installation being the reverse of removal. For 2004 through 2009 models, pry off the air registers on each side of the multi-display unit, remove the two screws at the bottom of the center panel beneath the radio, and pry off the center panel. Remove the multi-display unit, then the four mounting screws, sliding the radio out with its bracket, and disconnect the electrical connector. Separate the radio from its bracket, with installation being the reverse of removal. For 2010 and later models, use a plastic trim tool or a screwdriver wrapped with tape to carefully pry up and remove the integration control panel, pull up the rear of the lower center instrument cluster trim panel, and disengage the clips. Pry off the instrument cluster finish trim panel, remove the upper instrument panel trim piece at the right of the steering wheel while disconnecting the wiring, then remove the four radio mounting screws, releasing the claws as you pull the radio from the instrument panel and disconnecting the electrical connector. Remove the bracket from the radio if necessary, with installation being the reverse of removal. For door speakers, remove the door trim panel, drill out the speaker mounting rivets, disconnect the electrical connector, and remove the speaker from the vehicle, with installation being the reverse of removal. For upper instrument panel speakers in 2004 and later models, pry up the speaker assembly, disconnect the electrical connector, and remove the screws to disconnect the speaker from the grille, with installation being the reverse of removal. For upper door speakers, remove the cover panels for the outside mirrors, disconnect the speaker wiring, and remove the speaker, with installation being the reverse of removal. For instrument panel lower center speakers, remove the single screw and pry off the lower center instrument panel cover, disconnect the speaker wiring, and remove the speaker, with installation being the reverse of removal.
