This procedure covers removal and replacement of the roof-mounted radio antenna mast and base assembly on the 2012-2017 Toyota Camry.

Warnings

Tools required

Parts

• Roof antenna assembly × 1 — Toyota OEM 86337-06020 or equivalent
• Antenna base gasket/seal × 1 — Typically included with antenna assembly

Preparation

1. Park vehicle on level surface and turn ignition off
2. Ensure radio is turned off
3. Have a clean cloth or towel ready to protect headliner from dirt

Procedure

1. 1

   Access the antenna base from interior
   Open the rear passenger door on the driver's side. Using trim removal tools, carefully pry down the rear portion of the headliner near the antenna location to expose the antenna base mounting nut. You may need to remove the dome light assembly first by gently prying it down with a trim tool, then disconnecting the electrical connector.
2. 2

   Disconnect antenna cable
   Locate the antenna cable connection at the base of the antenna assembly. Press the release tab and pull the coaxial cable connector straight off the antenna base terminal. Note the routing of the cable for reinstallation.
3. 3

   Remove exterior antenna mast
   From outside the vehicle, unscrew the antenna mast by turning it counterclockwise by hand. Remove the mast completely and set aside. If the mast is corroded or stuck, apply penetrating oil and wait 10 minutes before attempting removal.
4. 4

   Remove antenna base mounting
   From inside the vehicle, use a 10mm socket with extension to remove the antenna base mounting nut. There is typically one nut securing the base to the roof panel. Support the antenna base from outside while removing the nut to prevent it from falling.

5. 5

   Remove antenna assembly from roof
   From outside the vehicle, carefully lift the antenna base assembly straight up and out of the roof opening. Remove the rubber gasket/seal from the roof opening and inspect it for damage or deterioration.
6. 6

   Clean mounting surface
   Clean the roof mounting surface around the antenna opening with a clean cloth. Remove any dirt, debris, or old sealant. Inspect the roof opening for rust or damage and address as needed before installing new antenna.
7. 7

   Install new antenna base gasket
   Position the new rubber gasket/seal onto the new antenna base assembly, ensuring it is properly seated in the groove. Verify the gasket is oriented correctly with any drain holes positioned toward the rear of the vehicle.
8. 8

   Install new antenna assembly
   From outside the vehicle, insert the new antenna base assembly through the roof opening, ensuring the cable passes through cleanly without pinching. Align the mounting stud with the hole in the roof panel. From inside, start the mounting nut by hand.
9. 9

   Secure antenna base
   Using a 10mm socket and torque wrench with extension, tighten the antenna base mounting nut to specification. Ensure the base gasket is compressed evenly and the assembly sits flush against the roof panel without gaps.

10. 10

    Reconnect antenna cable
    From inside the vehicle, push the coaxial cable connector firmly onto the antenna base terminal until it clicks into place. Gently tug the cable to verify it is securely connected.
11. 11

    Install antenna mast
    From outside the vehicle, thread the antenna mast onto the base by turning it clockwise by hand. Tighten until snug, but do not over-tighten as this may damage the threads.
12. 12

    Reinstall interior trim
    Carefully push the headliner back into position. If dome light was removed, reconnect the electrical connector and snap the assembly back into place. Ensure all trim pieces are properly seated and secured.

Reassembly

1. Verify headliner and all interior trim panels are properly reinstalled and secured
2. Check that antenna mast is vertical and properly tightened
3. Inspect exterior base for proper seal against roof with no gaps

Verification

• Turn on the radio and test AM/FM reception on multiple stations across the dial
• Compare signal strength to pre-repair condition - should be equal or improved
• Visually inspect the roof area for any water leaks during the next car wash or rain
• Verify antenna mast is stable and does not wobble or rattle while driving
