How to Change amp; Replace the Antenna Mast on a 1994 Mercedes S500

1. Loosen the nut securing the antenna mast to the driver side rear quarter panel, near the trunk lid, using an adjustable wrench.
2. Switch the vehicle's ignition on and turn on the radio. Quickly pull out the antenna mast and attached nylon cord from the rear quarter panel, while the power antenna motor attempts to extend the mast. The operation of the power antenna motor only lasts for a few seconds.
3. Shut off the radio and quickly make your way to the rear of the vehicle. With the power antenna motor running, hold the bottom metal portion of the new antenna with one hand, while feeding the attached nylon cord into the mounting base, located on the rear quarter panel.
4. Continue feeding the nylon cord into the mounting base, using a twisting motion, until the power antenna motor successfully pulls the nylon cable in automatically. Secure the new antenna mast to the base, using the supplied nut and an adjustable wrench.
5. Switch the vehicle's ignition off to finish the installation process.
