About the Metra 40-VW21 Antenna Adapter

Volkswagen uses a non-standard jack on its antenna cables, which can create a problem when you want to replace a broken antenna or connect an FM modulator to your system. This simple in-line adapter has a standard female Motorola antenna jack on one end, and a male Volkswagen/Audi plug on the other. Just connect your antenna cable to the adapter, plug it into your Volkswagen radio, and you're good to go. Warranty: 60 days.

Just connect your antenna cable to the adapter, plug it into your Volkswagen radio, and you're good to go. Warranty: 60 days.

If you're adding an FM modulator to your factory stereo, a second adapter is also required. One adapter will connect to your factory stereo, while the second connects to your factory antenna cable. Your FM modulator installs inline between the two adapters.
