Steering Wheel Control Interface
for Toyota/Lexus/Scion Vehicles
Rev. 031516
Page 1
Introduction & Features
Important Notes
The RP4.2-TY11 interface allows the replacement of a factory radio in select Toyota/Lexus/Scion vehicles and will retain
factory features such as steering wheel controls (SWC) and the factory audio amplier. This interface also allows you to
program two radio functions to each SWC button by using short press long press dual command functionality and also
provides outputs such as: vehicle speed sense (VSS), illumination, reverse trigger and parking brake.
1. Adjustment of the vehicle settings through the original radio’s vehicle settings menu will be disabled after installation of your
new radio. It is advised to make sure all settings are as you desire prior to removal of the original radio.
2. Does not retain Rear Seat Entertainment.
3. Speaker fading on factory amplied systems is only supported by the amplied output.
4. When using real time fade, if you have the fader set more to the front or back, upon start up the sound may begin at the default
setting and then quickly transition to your custom setting.
5. The USB-TY1 or USB-TY2 must be purchased in order to retain the factory USB port. Please refer to www.pac-audio.com to
see which harness you will need.
6. The CAM-TY11 or CAM-TY12 must be purchased in order to retain the factory reverse camera. Please refer to www.pac-
audio.com to see which harness you will need. If you do not have the harness required and need to retain the reverse camera,
please refer to Appendix A on Page 8 for hard wiring options.
