Specific instructions for removing a Pioneer stereo deck varies among vehicle makes and models; however, a certain set of procedures are universal in removing a unit for repair or replacement. You can have your Pioneer stereo removed by a technician at an aftermarket retailer or you can extract the stereo yourself and save the cost of labour.
Safely Removing the Pioneer Stereo
Before disconnecting any component from your vehicle, first disconnect the negative battery cable (or grounding cable) from your vehicle's battery. The grounding cable is the black cable that connects the negative lead of the battery to the frame or chassis of the vehicle. Use a Phillips-head screwdriver or 10mm tool (socket and ratchet or wrench) to loosen the cable's clamp bolt. Remove the clamp completely from the battery's negative lead.
Proceeding without disconnecting the grounding cable can lead to damage to the battery or the other components connected to the vehicle's battery.
Accessing the Pioneer Stereo
Specific instructions for removing a stereo deck varies among different vehicle makes and models. For proper instructions, consult your vehicle owner's manual.
Usually, gaining access to a stereo requires the removal of the panels surrounding the stereo mounting bracket. Use a trim panel removal tool to remove the panels. Any screws that secure the Pioneer stereo in the mounting bracket will be found behind the panels. Use a Phillips-head screwdriver to release the stereo.
For aftermarket-installed Pioneer decks, a faceplate adaptor will likely house the stereo. Use a trim panel tool to remove the frame of the adaptor.
Disconnecting the Pioneer Stereo
Once you have pulled the Pioneer stereo unit from the dash of the vehicle, it will still be connected via several groups of wires from the rear of the unit to the vehicle. Pull the wire groups from their outlets on the stereo. The wire groups are for the antenna, the speakers, the amplifier and the power supply. There also may be groups for an equaliser, a satellite radio receiver and an iPod or MP3 player.
If the stereo is connected using a wiring harness adaptor, disconnect the wiring harness leads from the Pioneer unit. Leave the adaptor connected to the wiring from the vehicle for easy connection to a new stereo.
