Tools required

Parts

• Replacement radio/head unit × 1 — Use OEM specification or compatible aftermarket unit
• Trim panel clips (if broken during removal) — Toyota 90467-10188 or equivalent

Preparation

1. Park vehicle on level surface and set parking brake
2. Turn ignition off and remove key/fob from vehicle
3. Disconnect battery negative terminal using 10mm wrench
4. Wait 90 seconds for airbag system to discharge
5. Gather replacement head unit and verify compatibility with vehicle harness

Procedure

1. 1

   Remove lower instrument panel trim
   Use plastic trim tools to carefully pry out the lower center console trim panel below the radio. Start from the bottom edge and work around the perimeter. Release all clips and set panel aside safely to avoid scratches.
2. 2

   Remove climate control trim panel
   Carefully pry the climate control and radio surround trim panel starting from the bottom edges. Work your way around the perimeter, releasing all retaining clips. Disconnect the hazard switch connector if equipped on this trim piece. Remove panel completely.
3. 3

   Remove radio mounting bolts
   Locate and remove the four 10mm bolts securing the radio bracket to the instrument panel frame (two on each side). These may be covered by small access holes. Keep bolts organized for reinstallation.

   Pull radio unit forward
   Carefully pull the radio/head unit forward from the dash opening approximately 4-6 inches. Support the unit with one hand while accessing rear connectors. Do not pull harness connectors yet.
5. 5

   Disconnect antenna cable
   Locate the antenna cable connector on the back of the radio unit. Press the release tab and pull straight back to disconnect. The connector is typically black with a coaxial fitting.
6. 6

   Disconnect main harness connectors
   Disconnect the main electrical harness connectors from the rear of the radio. Press the locking tabs and pull connectors straight back. There are typically 2-3 large multi-pin connectors depending on the audio system configuration (base, premium, or JBL).
7. 7

   Remove radio unit
   With all connections disconnected, carefully remove the radio/head unit from the vehicle. Check that no wires are snagged or pinched.
8. 8

   Transfer mounting brackets if needed
   If installing an aftermarket unit, remove the factory mounting brackets from the old radio using the appropriate screws or bolts. Transfer these brackets to the new unit in the same orientation. If installing OEM replacement, skip this step.
9. 9

   Connect new radio harnesses
   Connect all electrical harness connectors to the new radio unit. Ensure each connector clicks and locks securely. Connect connectors in reverse order of removal: main harness connectors first, then antenna cable last. Verify proper seating of all connections.
10. 10

    Test radio before final installation
    Reconnect battery negative terminal temporarily. Turn ignition to ACC or ON position and verify radio powers on, all buttons function, and audio output works through all speakers. Check backup camera display if equipped. If all functions work, disconnect battery again before proceeding.
