How do you change a CD player in a Nissan Quest?

To change a CD player in a Nissan Quest, first disconnect the car battery to ensure safety. Remove the trim panel surrounding the stereo using a trim removal tool, then unscrew the mounting screws holding the CD player in place. Disconnect the wiring harness and antenna from the back of the old CD player, then connect these to the new unit. Finally, secure the new CD player in place, reattach the trim panel, and reconnect the battery.
