Q: How do you remove and install the radio and speakers on Toyota Highlander?
A: To remove the radio from 2013 and earlier Highlander and 2009 and earlier Lexus models, start by removing the center trim panel, then take out the radio and heater/air conditioning control assembly mounting bolts, pulling out the cluster enough to disconnect the electrical connectors. Next, pull out the radio and heater/air conditioning control assembly, disconnecting the electrical connectors, and detach the radio unit from the mounting bracket by removing the bolts from each end. For installation, reverse the removal steps. For 2014 and later Highlander models, disconnect the negative battery cable, remove the center upper trim panel and two center air registers, then take out the radio unit fasteners, noting that two fasteners are located behind the radio unit in the air register openings. Pull the radio unit and bracket forward to release the retaining clip and disconnect the electrical connectors, then remove the fasteners and lower the display unit from the roof, with installation being the reverse of removal. For 2010 through 2015 Lexus models, disconnect the negative battery cable, remove the shift lever, carefully pry up the center console top panel, remove the knee bolster panel, and disconnect the switches. Remove the two lower center trim panels from under the radio assembly, take out the radio unit fasteners, and carefully pry the radio and air conditioning panel out from the instrument panel, disconnecting the electrical connectors. Note that the radio assembly cannot be removed from the trim panel, and if replacing the radio unit, remove the air registers and hazard switch. Installation is the reverse of removal. For 2016 and later Lexus models, disconnect the negative battery cable, remove the two top trim panels from the edges of the floor console, and carefully pry out the narrow center trim panels. Locate and remove the vertical radio assembly fasteners, pull the radio unit and bracket forward to release the retaining clip, and disconnect the electrical connectors. Installation is the reverse of removal. For door speakers, remove the door trim panel, disconnect the electrical connector, remove the speaker mounting screws, and take out the speaker, with installation being the reverse. For tweeters located in the front doors, follow a similar process. For instrument panel speakers, carefully pry the speaker cover panel(s) up, disconnect the electrical connector, remove the fasteners, and detach the speaker. For quarter trim panel speakers, remove the quarter trim panels, disconnect the electrical connector, and detach the speaker. For the lift gate speaker, remove the lift gate panel, disconnect the electrical connector, and detach the speaker, ensuring not to touch the speaker cone. For the overhead video display unit in Highlander models, use a plastic trim tool to pry the corners of the trim panel, disconnect the electrical connector, and lower the display unit. For seat back video display units in Lexus models, raise the video monitor, pry the lower edge of the cover trim panel, remove the fasteners, disconnect the electrical connector, and remove the unit from the seat back, with installation being the reverse of removal.
