Volkswagen Audi Antenna Adapter

This Metra 40-VW18 adapter connects a factory screw-on antenna cable to an aftermarket radio with a female Motorola jack. It is a car electronics accessory designed for Volkswagen and Audi vehicles. The black plastic housing measures 8.75 inches long, 3.00 inches wide and 0.50 inches high. It weighs 0.06 lbs and arrives in new condition.

Installers Replacing Factory Radios

The adapter suits anyone fitting an aftermarket head unit into a compatible Volkswagen or Audi while keeping the original antenna. It will not help owners of vehicles that already use a standard Motorola antenna plug. Buyers needing amplified antenna support or a different connector style should look at another product.

Check Connector Type Before Ordering

Verify that the vehicle currently uses a factory screw-on antenna connector before purchase. Confirm the aftermarket radio has a female Motorola antenna input. No other vehicle interface or dashboard dimension needs checking for this specific accessory.

Questions about this item

Will the Metra 40-VW18 connect directly to my factory screw-on antenna cable?

Yes, the adapter converts the European factory screw-on connector to a female Motorola plug for aftermarket radios.

Does the 0.50" height allow the adapter to fit behind a double-DIN head unit?

At half an inch tall, the low-profile body typically clears the shallow cavity behind most double-DIN installations.

How can I confirm the antenna signal is passing through after installation?

Tune to a known local station; clear reception indicates the factory cable, adapter and aftermarket tuner are all connected correctly.
