Remove and replace the roof-mounted shark fin antenna assembly on the 2017 Maserati Levante, including disconnecting the cable and resealing the roof penetration.

Warnings

Tools required

Parts

• Shark fin antenna assembly × 1 — Use OEM specification
• Antenna base gasket/seal × 1 — Use OEM specification
• Headliner retaining clips (if damaged) × 3 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key fob from vehicle interior
3. Allow vehicle to sit for 5 minutes to allow infotainment system to fully power down
4. Ensure roof is clean and dry around antenna area
5. Gather all tools and replacement parts before beginning

Procedure

1. 1

   Remove rear overhead console trim
   From inside the vehicle, use plastic trim tools to carefully pry down the rear section of the headliner near the rear seats. Start at the edges and work toward the center. Release the retaining clips securing the headliner panel directly below the antenna location. You may need to remove the overhead grab handles by unscrewing their cover caps and removing the mounting screws.
2. 2

   Disconnect antenna cable connector
   Locate the antenna cable connector above the headliner. Press the release tab and pull the connector straight down to disconnect it from the antenna base. Note the routing of the cable for reinstallation. If there are multiple connectors (GPS, satellite radio, cellular), label them with tape to ensure correct reconnection.
3. 3

   Access antenna mounting from exterior
   From outside the vehicle, inspect the shark fin antenna base. Clean any dirt or debris from around the base perimeter. The antenna is secured by either a central mounting nut accessible from below, or by perimeter mounting screws depending on the specific antenna type installed.
4. 4

   Remove antenna mounting hardware
   Using the T20 Torx driver, remove the mounting screws or central mounting nut securing the antenna to the roof. There are typically 3-4 fasteners. Support the antenna from above as you remove the final fastener to prevent it from falling. Carefully lift the antenna assembly straight up and away from the roof, breaking the seal of the gasket.
5. 5

   Remove and inspect old gasket
   Carefully remove the old antenna base gasket from the roof. Inspect the roof mounting surface for any damage, corrosion, or debris. Clean the entire mounting surface thoroughly with isopropyl alcohol and a lint-free cloth. Ensure the surface is completely dry before proceeding. Check that the roof opening is free of water or moisture.
6. 6

   Prepare new antenna assembly
   Unpack the new antenna assembly and verify all components are included. Position the new gasket on the antenna base, ensuring it is seated properly in the gasket channel. Do not apply any additional sealant unless specified by the manufacturer, as the gasket provides the necessary seal.
7. 7

   Connect antenna cables
   From inside the vehicle, guide the new antenna cable(s) through the roof opening. Connect each cable to its corresponding connector, ensuring you hear or feel a positive click. Gently tug each connection to verify it is secure. Match any labels you made during disassembly.
8. 8

   Install and secure new antenna
   From outside the vehicle, carefully align the antenna base with the mounting holes in the roof. Ensure the gasket remains properly positioned. Insert all mounting screws or the central nut and hand-tighten. Torque the mounting hardware in a cross-pattern to the specification listed for Mounting Bolts to ensure even gasket compression and proper sealing.

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Reinstall headliner trim
   From inside the vehicle, push the headliner panel back up into position, ensuring all retaining clips engage properly. Reinstall any grab handles or trim pieces removed earlier, torquing their fasteners to the Cover Screws specification if applicable. Verify the headliner sits flush with no gaps.
   Torque spec

   Cover Screws11 Nm (8 lb-ft)

Reassembly

1. Ensure all interior trim panels are properly seated and all clips are engaged
2. Verify no tools or parts were left in the headliner area
3. Inspect exterior antenna base for proper alignment and complete gasket sealing

Verification

• Start the vehicle and verify the infotainment system boots without fault codes
• Test AM/FM radio reception on multiple stations
• Test satellite radio functionality (if equipped and subscribed)
• Verify GPS navigation acquires satellite signal within 2-3 minutes
• Check for any warning lights or messages related to communication systems
• Inspect antenna installation for water leaks by gently spraying water around the base and checking for moisture inside (if weather permits)
• Verify all interior trim panels are secure with no rattles
