RP4-MZ11
& Steering Wheel Control
Interface for MazdaVehicles
Introduction & Features
Important Notes
The RP4-MZ11 interface allows the replacement of a factory radio in select Mazda vehicles with MS-CAN radios. Using
this interface will retain factory features such as steering wheel controls (SWC), programming of the clock on the OEM
LCD screen, vehicle information on the OEM LCD screen and the BOSE amplifier when the original radio is removed. Use
of this interface also allows you to program two radio functions to each SWC button by using short press long press dual
command functionality. The RP4-MZ11 also provides data bus driven outputs such as retained accessory power (RAP),
vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
1. The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the
vehicle (see next page for setting chart).
2. The LED will flash whenever a SWC button is pressed
3. The interface comes pre-programmed for all of the vehicles factory SWC functions and does not require programming unless you wish
to re-assign the SWC functions or utilize short press long press dual command functionality. The SWC can always be restored to default
settings by pressing and releasing the program button on the side of the interface once and waiting 7 seconds for the LED to flash 4 times.
4. The settings menu cannot be accessed in the 2013 Mazda 3 with navigation.
5. If using this interface in a Mazda CX-5 or 2014+ Mazda 6, all vehicle settings must be finalized before removing the factory radio.
6. If using in a veheicle equipped with a factory BOSE system, it may be necessary to use a Line Output Converter or connect RCAs to the
speaker wire and use the aftermarket radio’s low level outputs.
