The Honda Civic was redesigned for the 2001 model year, marking the start of its seventh generation. Four trim lines were available, starting with the low-end DX, then moving up to the HX, LX and EX. All trim levels came standard with an AM-FM radio; HX and LX models came with a cassette player, and EX models included a CD player. Replacing the stock radio with an aftermarket unit isn't a difficult process, but you do have to remove portions of the center console to get to some hidden bolts that hold the radio and bezel to the dash.
Items you will need
- 8 mm socket
- Flat-head screwdriver
- Electrical tape
- Phillips screwdriver
- 10 mm socket
- Radio installation kit
- Wiring harness adapter
- Butt connectors
- Wire crimps
- Antenna adapter -- for non-Pioneer radios
Open the hood and loosen the negative battery terminal with an 8 mm socket and ratchet. Pull the negative battery cable off the battery and slide it next to the battery. Wrap electrical tape around the end of a flat-tip screwdriver and pry upward around the edges of the center console box – the trim panel to the rear of the center console that has a small storage compartment and is next to the E-brake handle. Remove the console box.
Turn the shifter knob counterclockwise and remove it, if your car has a manual transmission. Find the two screws that were hidden by the console box and remove them with a Phillips screwdriver. Remove the screw from each side toward the rear of the console, near the floor. Remove the push-pin retainer from each side of the front of the console the console. Lift up on the rear of the console and pull it toward the rear of the car. Lift the entire console and remove it from the car.
Pry out the bezel that houses the 12-volt accessory socket. Squeeze the locking arm and disconnect the wiring harness from the back of the accessory socket. Remove the bezel. Follow the wiring harness for the accessory socket until you find where it clips onto a small metal crossmember in the dash. Remove the two bolts next to the wiring harness retainer, using a 10 mm socket and ratchet.
Pry outward around the edges of the radio-and-storage-compartment bezel when you've released all of the retaining clips pull the bezel outward from the dash. Disconnect the wiring harness and antenna wire from the radio. Disconnect the wiring harnesses from the push-button controller and the heater and air-conditioning control module. Remove the bezel from the dash.
Remove the two screws that hold the push-button controller to the back of the bezel and remove the controller. Pull on all three control knobs to remove them, then remove the three screws that hold the heater and air-conditioning control module to the back of the bezel. Remove the heater and air-conditioning control module.
Remove the screws that hold the radio and small storage compartment to the radio bracket. Slide the radio out of the bezel, followed by the storage compartment. If you're not replacing the radio with an aftermarket unit, skip to the "Installation" section, but see the "Tips" section first, regarding the radio lock code and how to obtain it if you don't have it.
Aftermarket Radio Preparation
Open the radio installation kit and follow the directions to build a new radio housing – this housing makes the radio sit flush with the bezel and includes a new, larger storage pocket. Remove the sleeve from the aftermarket radio and slide it into the new housing where the radio will sit. Bend the little metal tabs around the edge of the sleeve outward to secure the sleeve to the housing. Slide the new housing into the bezel and secure it to the radio bracket with the screws that originally held the radio and storage pocket.
Open the new wiring harness adapter and the wiring harness for the aftermarket radio. Slide the pre-cut insulation off the tips of all the wires. Slide a butt connector onto each of the wires for both wiring harnesses. View the wiring diagram for the harness adapter and the aftermarket radio – don't trust the color coding, as they may vary from the aftermarket unit and the harness adapter manufacturers.
Match one of the wires from the radio's wiring harness with the wiring harness adapter. Twist the two wires together and slide a butt connector over the bare wire. Crimp the connector, then use a lighter to apply heat to the ends of the butt connector and shrink the tubing. Repeat this process for each wire until you've connected and sealed all of them. Wrap electrical tape around the wires working from the base of harness adapter to the base of the aftermarket radio wiring harness.
Connect the wiring harness adapter to the harness for the stock radio. Plug the antenna wire into an antenna adapter designed for the brand of your aftermarket radio, if it isn't made by Pioneer.
Install the push-button onto the back of the radio bezel and tighten the two mounting screws just snug. Install the heater and air-conditioning control module onto the back of the bezel and tighten the three mounting screws just snug. Push the control knobs onto the heater and air-conditioning control module from the front side of the bezel.
Hold the bezel close to the dash and connect the wiring harnesses to the heater and air-conditioning control module and the push-button controller. Guide the aftermarket radio harness and the antenna wire through the sleeve for the aftermarket radio, or connect the wiring harness and antenna to the stock radio. Push the bezel into the dash and tap around the edges to engage the locking clips. Install the two bolts through the small metal crossmember and into the radio bracket. Tighten them just snug.
Push the bezel into the dash and tap around the edges to secure it. Lower the center console into place and guide the shifter through the leather boot, if your Civic has a manual transmission. Install the push-pin retainers at the front of the console. Install the screws on the side of the console toward the rear and tighten them snug. Install the two screws through the hole in the top of the console and tighten them snug.
Guide the center console box into the hole in the center console and tap around the edges to secure it in place. Install the shifter knob, if your Civic has a manual transmission. Skip to Step 6 if you didn't install an aftermarket radio.
Plug the wiring harness and antenna adapter into the aftermarket radio. Push the wires into the dash and slide the radio into the sleeve until you feel it lock into place. Install the finishing ring around the edge of the radio and install the radio face.
Connect the negative battery cable to the battery and tighten the cable. Shut the hood. You may experience a rough idle and poor shift quality on automatic transmissions until the powertrain control module relearns idle control and shift values– this will clear up after several miles of driving.
- The anti-theft code for the stock radio is normally on a card in the owners manual. If you can't find the card, write down the serial number from bottom of the radio before you install it. Drive to a local Honda dealership and tell them you need a radio unlock code. Once you have the code, type it into the radio using the six preset buttons on the bottom of the radio.
