About the Axxess XSVI-1785-NAV Wiring Interface

Axxess XSVI-1785-NAV

The Axxess XSVI-1785-NAV wiring interface lets you replace the factory radio in your Mercedes-Benz while retaining accessory (12-volt) power and retained accessory power (R.A.P.). The interface also gives you the parking brake, reverse, and vehicle speed sensor (V.S.S.) outputs you'll need to install a navigation receiver.

Product Research


Vehicle Compatibility: The Axxess Integrate XSVI-1785-NAV interface module allows you to replace the factory radio in select 2001-2004 Mercedes vehicles with an aftermarket head unit, while retaining important factory features and functions. The XSVI-1785-NAV can be utilized in the following Mercedes-Benz vehicles equipped with non-amplified factory audio systems or when bypsssing the factory amplified audio system.

Make Model Year
Mercedes C Class 2001-2004
CLK Class 2004
CLK500 2003
CLK55AMG 2003

R.A.P. (Retained Accessory Power): The R.A.P. (Retained Accessory Power) function, where power is supplied to the radio after the ignition is shut-off until one of the front doors are opened, is retained by the XSVI-1785-NAV.

Accessory Output:  In these Mercedes vehicles listed above, there is no 12-volt accessory wire currently in the factory harness making the installer run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The XSVI-1785-NAV is designed to provide a 12-volt, 10-amp switched accessory output along with the rest of the wires needed to install an aftermarket radio.

Navigation Outputs: The XSVI-1785-NAV also provides essential wires required for aftermarket radios that have navigation. Provided are VSS (Vehicle Speed Sense), Reverse, and Parking Brake. This cuts down the installation time since the installer does not have to look for these wires in the vehicle.

Optional SWC Adapter: You can add the the Axxess ASWC-1 Steering Wheel Control Interface (120ASWC1, sold separately) to retain your vehicle's factory steering wheel controls.
