- Locate the car battery in the trunk, typically by the rear tire well.
- Lift the carpet flap to access the battery.
- Using a 10mm socket, loosen the bolt holding the positive terminal to the connector.
- Remove the positive terminal connector. Wiggle it free if necessary.

5.2. Removing the Old Head Unit
- Use a pry tool (plastic is recommended to avoid damage) to carefully remove the trim around the head unit in the center console. Start from the bottom corners and work your way up.
- Once the trim is loose, gently pull it back. Most components in the center console are attached to this trim.
- Disconnect the plugs from the climate control unit (bottom), the clock (top), and the traction control/hazard light section (under the clock). There are typically three plugs at the bottom and two at the top.
- After disconnecting all plugs, the trim panel can be fully removed.
- Locate the four Phillips head screws holding the old radio (head unit) in place, one at each corner. Remove these screws.
- Carefully pull the radio out at an angle to access the plugs at the back. There is usually one large central plug. Disconnect it.
