The RP4-AD11 interface allows the replacement of a factory radio in select Audi vehicles with LSFT-CAN databus radios.

Using this interface will retain factory features such as steering wheel controls (SWC) and the factory audio amplier

whenever 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-AD11 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 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 ash 4 times.

3. The LED will ash whenever a SWC button is pressed.

RP4-AD11 Radio Replacement & Steering Wheel Control Interface for Audi Vehicles Testing & Verification 1. Turn the ignition on. The LED on the interface will turn on & the +12v accessory wire will turn on. 2. Turn on the radio & check balance & fade. Note: Factory amplified Systems will not fade as neither the aftermarket radio or the RP interface have the ability to control the amplifier’s fader. 3. Verify that the factory subwoofer (if present) is playing 4. Verify that all SWC are functioning properly.
