Metra Antenna Adapter

This antenna adapter lets you connect an aftermarket receiver to the factory antenna cable in select 2007-08 Audi, 2008-up Mercedes-Benz, and 2009-up Volkswagen vehicles. The adapter has an OEM female plug on one end and a Motorola male plug on the other. Installation note: A blue wire is attached to the antenna adapter. When installing the adapter, the blue wire should be connected to the antenna turn-on lead of your new car stereo. Please check the stereo's manual for more information. You'll need Metra's 40-EU66 adapter if you're installing an FM modulator with your factory radio. Warranty: 1 year.
