Using a plastic trim removal tool, gently pry the surrounding ceiling panel to expose mounting screws and wiring harnesses.
Remove the screws securing the unit to the ceiling.
Carefully disconnect all wiring harnesses connected to the system, noting their orientation and location for reinstallation.

Removing the Rear Entertainment System

Once the unit is accessible, follow these steps to remove the rear entertainment system:

Ensure all wiring connectors are detached by gently pressing release tabs and pulling connectors straight out.
Remove any additional screws or clips holding the system in place.
Lower the unit carefully and place it on a soft surface to avoid scratches or damage.

If replacing the system, compare the new unit with the old one to verify compatibility and confirm all connectors fit appropriately.
