Features

Vehicle Compatibility: Vehicle Compatibility: The Scosche MZ07SR radio replacement interface module is designed specifically for select Mercedes vehicles with factory non-amplified audio systems that feature a Fakra-style connector.

Make Model Year
Mercedes C Class 2005-2007
R Class 2006-2013
ML 2006-2011
Sprinter 2007-2015

+12V Accessory Output: In these Mercedes vehicles, there is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The MZ07SR is designed to provide a +12V accessory switched accessory output.

Steering Wheel Controls: The MZ07SR also includes a steering wheel control output, which allows you to keep your vehicle's factory steering wheel controls when replacing the factory radio with an aftermarket head unit that features a SWC input. No additional interface or programming is necessary.

Navigation Outputs: The MZ07SR provides navigation outputs for reverse, vehicle speed pulse, and parking brake - making installation of aftermarket navigation receivers much simpler and less time consuming.

Wiring Color Chart: The following wires of the included wiring harness will need to be hardwired to your new aftermarket stereo's harness.
