Radio Replacement and 

Steering Wheel Control Interface 

for Toyota / Lexus / Scion Vehicles

RP4.2-TY11

Default Steering Wheel Control Programming

IMPORTANT! 

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, utilize short press long press dual command functionality, or 

assign the programmable 12v output to a SWC button. 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 3 times.

Optional Steering Wheel Control Programming

If you wish to re-assign the SWC functions, utilize short press long press dual command functionality, the interface must be 

programmed in the specific order shown in the chart on page 5. If you come across a function in the chart that your steering 

wheel does not have, or you do not want to program, press and release the programming 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.

Short Press Long Press Dual Command Functionality

This feature allows you to assign two aftermarket radio functions to each of the vehicles SWC buttons. It can be used with as 

many of the buttons as the user likes or none at all. When this functionality is implemented, quickly pressing and releasing a 

SWC button will initiate the short press command while pressing and holding a SWC button for longer than two seconds will 

initiate the long press command. Please note that no long press commands are programmed by default. If you wish to assign 

dual command functionality to the SWC please follow the programming steps below.
