Scosche Wiring Interface

You want to upgrade the radio in your 2005-15 Mercedes-Benz, but you don't want to lose important factory features. The MZ07AR interface retains your steering wheel audio controls (if present) and your factory phone buttons, if you're installing a car stereo that supports those features. It also provides the 12-volt accessory output, as well as the connections needed for a car stereo with GPS, including reverse, speed pulse, and parking brake. Warranty: 60 days.
