Remove and replace the roof-mounted cellular/GPS antenna assembly on the 2022 Rivian EDV 500 electric delivery vehicle.

Warnings

Tools required

Parts

• Roof antenna assembly × 1 — Use OEM specification
• Antenna base seal/gasket × 1 — Use OEM specification
• Push-pin retainers × 6 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V accessory battery located in front compartment
3. Wait minimum 5 minutes for capacitor discharge
4. Ensure roof surface is clean and dry
5. Set up stable ladder or platform for safe roof access
6. Mark antenna cable routing with masking tape if replacing entire assembly

Procedure

1. 1

   Access interior headliner
   From inside the cargo area, locate the headliner panel directly below the antenna location (typically center-rear of roof). Use plastic trim tools to carefully release the headliner retaining clips starting from the rear edge. Lower the headliner panel approximately 6-8 inches to expose the antenna cable routing and mounting hardware. Support the headliner to prevent damage.
2. 2

   Disconnect antenna electrical connector
   Locate the antenna cable connector attached to the vehicle wiring harness. Press the locking tab and carefully disconnect the connector. If equipped with multiple antenna cables (cellular, GPS, AM/FM), label each connection with tape to ensure correct reassembly. Use wire terminal release tool if connector is difficult to separate.
3. 3

   Release cable from interior routing clips
   Follow the antenna cable from the connector toward the roof penetration point. Release the cable from all routing clips and wire management channels using the trim removal tool. Note the exact routing path for reinstallation. Carefully free approximately 24 inches of cable length to allow removal through roof opening.
4. 4

   Access exterior antenna base
   Using the step ladder, safely access the vehicle roof. Locate the antenna assembly on the roof surface. Clean any dirt or debris around the antenna base to prevent contamination from falling into the vehicle interior during removal.
5. 5

   Remove antenna mounting fasteners
   Using the appropriate Torx driver (typically T25 or T30), remove the fasteners securing the antenna base to the roof panel. Most Rivian EDV antennas use 3-4 fasteners in a circular pattern. Keep fasteners organized for reinstallation. Support the antenna assembly to prevent it from falling.
6. 6

   Extract antenna assembly from roof
   Carefully lift the antenna assembly from the roof opening. Have an assistant inside the vehicle guide the antenna cable through the roof penetration point to prevent snagging. Remove the assembly completely and inspect the roof opening for damage or debris. Remove the old antenna base gasket.
7. 7

   Inspect and clean mounting surface
   Thoroughly clean the roof mounting surface around the antenna opening using shop towels. Remove all old adhesive residue or gasket material. Inspect the roof panel for corrosion, paint damage, or stress cracks. Check that the roof drain channels are clear of debris.
8. 8

   Prepare new antenna assembly
   Unpack the new antenna assembly and verify all components are included. Install the new base gasket onto the antenna mounting flange, ensuring proper alignment. If the gasket has adhesive backing, remove the protective liner. Inspect cable connectors for damage or corrosion.
9. 9

   Route new antenna cable
   From the exterior, feed the new antenna cable through the roof opening. Have an assistant inside guide the cable to prevent binding. Route the cable through the same path as the original, securing it in all factory wire management clips and channels. Ensure adequate slack for connection without tension.
10. 10

    Install antenna to roof
    Position the new antenna assembly onto the roof mounting location, aligning the mounting holes with the roof panel. Ensure the base gasket is properly seated all around the perimeter. Hand-start all mounting fasteners before tightening. Tighten fasteners in a cross-pattern sequence to ensure even gasket compression. Do not overtighten as this may damage the gasket or roof panel.
11. 11

    Connect interior wiring
    Inside the vehicle, connect the antenna cable to the vehicle harness connector, ensuring a positive lock engagement. Match any labeled connections to their original positions. Verify connections are secure by gently pulling on each connector.
12. 12

    Reinstall headliner panel
    Carefully raise the headliner panel back into position, ensuring no wires are pinched. Align the panel with all mounting points and press firmly to engage the retaining clips. Verify the headliner is flush and properly seated along all edges.
13. 13

    Reconnect battery and initialize system
    Reconnect the 12V accessory battery in the front compartment. Turn the vehicle to ON position and allow the electrical system to initialize. Monitor the instrument cluster for any antenna-related fault codes or warnings.

Reassembly

1. Ensure all interior trim panels are fully seated with no gaps
2. Verify antenna cable has no tension or sharp bends in routing
3. Check that roof gasket is uniformly compressed around entire antenna base
4. Confirm no water leaks around antenna base by performing water test if possible

Verification

• Turn vehicle to ON position and verify no antenna-related fault codes appear
• Test cellular connectivity by accessing vehicle telematics features (if equipped)
• Verify GPS signal reception using navigation system
• Test AM/FM radio reception if antenna includes radio functionality
• Inspect antenna base from exterior for proper sealing and alignment
• Perform visual inspection of headliner for proper fitment
• If telematics issues occur, vehicle may require dealer programming to re-pair antenna module
