Frequently Asked Questions - RP4-MZ11 PAC

What is the PAC RP4-MZ11 interface used for?

The PAC RP4-MZ11 is an aftermarket radio interface for select Mazda vehicles. It retains factory features like steering wheel controls, clock, vehicle information, and BOSE amplifier when replacing the factory radio.

Which Mazda vehicles are compatible with the RP4-MZ11?

Compatible vehicles include Mazda 3 (2004-2009), Mazda 5 (2010), Mazda 6 (2009+), CX-5 (2013+), CX-7 (2007-2009), CX-9 (2007+), Miata, and RX-8. Some models may have limitations on VSS, reverse, or parking brake outputs.

How do I set the radio select switch on the RP4-MZ11?

Before plugging the interface into the vehicle, adjust the rotary switch on the side to match your aftermarket radio brand. Refer to the setting chart in the manual (e.g., Alpine=1, Pioneer=7, etc.).

Can I program the steering wheel controls to different functions?

Yes, the SWC can be reprogrammed. Press and hold the programming button until the LED turns off, then follow the steps to assign each button. The default assignments can be restored by pressing the program button once and waiting 7 seconds for 4 LED flashes.

How do I set the clock on the OEM LCD after installation?

Press and hold the Mode button on the steering wheel until 'Setup Menu' appears. Navigate to 'Set Clock' and select the appropriate clock set mode for your vehicle. Follow the on-screen instructions or the chart in the manual.

Yes, the interface retains the BOSE amplifier. Fader adjustment must be performed through the interface's vehicle settings menu (Amp Settings) for premium amplified systems.

What should I do if my steering wheel controls are not working properly?

First, verify the radio select switch setting. If still erratic, perform a SWC recalibration: press and hold the programming button for 7 seconds until the LED flashes, then press each steering wheel button in the specified order. This will restore default calibration.

Does the RP4-MZ11 support rear seat entertainment (RSE)?

Yes, it allows the factory DVD player and rear screen to function independently. Audio is played through headphones, not the aftermarket radio. Video cannot be passed to the aftermarket head unit.

Can I update the firmware on the RP4-MZ11?

Yes, firmware updates are available using the PAC-UP interface updater (sold separately). Check www.pac-audio.com/firmware for the latest updates.

What is the accessory output rating of the interface?

The red wire in the interface connector provides a 12V accessory output rated at 1 amp. It turns on with ignition and is used for the aftermarket radio's power antenna or other accessories.

USER MANUAL RP4-MZ11 PAC

Introduction & Features

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. 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.

Important Notes

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 below for setting chart).
2. If using this interface in a Mazda CX-5, all vehicle settings must be finalized before removing the factory radio.
3. When the interface is first plugged into the vehicle the LED will flash indicating that it is initializing. Once initialization is complete the LED will illuminate and should be on at all times when the interface is on.
4. The following vehicles will not provide a VSS signal as this information is not on the data bus: RX-8, 2007-2009 CX-9 w/non-nav radio, Miata
5. The following vehicles will not provide a reverse output as this information is not on the data bus: RX8, 2007-2009 CX7, 2010 Mazda 5, Miata
6. The following vehicles will not provide a parking brake output as this information is not on the data bus: RX-8, Miata
7. The following vehicles have a speed based parking brake wire that will provide a negative trigger until the vehicle is going at least 4 mph: 2007-2009 CX-9, 2007-2009 CX-7
8. The LED will also flash whenever a SWC button is pressed
9. 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 to different buttons. 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.
10. The LED will flash whenever a SWC button is pressed.

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.
2. Make all connections as described in the chart on page 1. 2013+ Mazda CX5 - Connect the blue wire in the 24 pin vehicle harness to the green/white wire in the 16-pin RP harness. This is necessary for the Bluetooth SWC to function with the aftermarket radio. This vehicle must also use the orange/white wire in the Interface Connector.
3. Connect the SWC wire according to the chart on page 1 (aftermarket radio MUST support a wired remote input).
4. If you wish to reassign the SWC buttons to different functions follow the programming instructions in the next section.

Accessing Vehicle Settings (vehicles equipped with OEM LCD)

To access the vehicle setting menu, press and hold the Mode button on the SWC until "Setup Menu" is displayed on the LCD screen. Use the Arrow Down on the SWC to scroll through the options. Once the option you wish to select is displayed, press the Mode button on the SWC to advance to the next step. Follow the instructions listed below under each option to make changes.

Change Text - Allows you to enter custom text for the LCD screen's default display. Once this is selected, you can use the Volume Up & Down buttons to select the character position and the Arrow Up & Down buttons to select the character. Once you have set your custom text, do not press any buttons for 8 seconds and the programming function will time out and return to the default display.

Rear Seat Entertainment (RSE); If equipped

The RP4-MZ11 will allow the DVD player and rear screen to function independently from the new radio. A/V will be passed from the factory DVD player to the rear screen and audio can be heard through the headphones. A/V cannot be passed from the factory DVD player to the aftermarket head unit.

SWC Recalibration

SWC re-calibration is necessary when the SWC operation is erratic or non-existent. This process re-calibrates the SWC values to the RP4 interface so it will know what they can be set to for button function assignment. The interface must be programmed in the specific order shown in the chart below. If you come across a function in the chart that your steering wheel does not have you MUST press and release the program button on the side of the interface to skip that function. The LED will flash off and on confirming that you have successfully skipped that function and are ready to proceed to the next one.

The SWC and radio command assignments can always be restored to default values by entering re-calibration mode (Steps A-C) and not pressing any buttons. After 7 seconds the re-calibration mode will time out and all default values will be restored.

Step A.

Turn the vehicle ignition to the ON position.

Step B.

Press and hold the programming button for 7 seconds

LED will begin flashing

Step C.

Release the programming button.

Step D.

Within 7 seconds, press and release the button that is to be learned on the steering wheel.

The LED will turn off during this process.

Step E.

Release the button.

The LED will turn back on.

Step F.

If you need to program more buttons, repeat steps D & E for each additional function on the steering wheel.
