Radio Replacement Interface (for Toyota/Scion/Lexus): The PAC RadioPRO RP4.2-TY11 radio replacement interface is designed for 2003-2016 Toyota, Lexus, and Scion vehicle models. The module enables installation of an aftermarket radio while retaining the factory steering wheel control functions as well as maintaining compatibility with the factory JBL and JBL Synthesis amplified audio systems, the built-in 3.5mm auxiliary audio jack, and factory LCD. The built-in USB connection and back-up camera can also be retained in conjunction with an optional adapters (sold separately).
- 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.
- Does not retain Rear Seat Entertainment (RSE).
Vehicle Compatibility: The RadioPRO 4 RP4.2-TY11 is compatible with the following 2001-2016 Toyota, Scion, & Lexus vehicles.
- Only compatible in Toyota Avalon vehicles equipped with a JBL system.
- Not compatible in Lexus vehicles equipped with factory navigation.
Radio Select Switch: The radio select switches on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle. The RP4.2-TY11 is compatible with Alpine, JVC, Kenwood, Clarion, Pioneer, Sony, Jensen, Fusion, Advent, Boyo, Dual, Lightning Audio, Rockford Fosgate, and Visteon aftermarket radios (see owner's manual for appropriate dip-switch setting).
For Amplified & Non-Amplified Systems: The PAC RadioPRO RP4.2-TY11 can be used in vehicles with amplified & non-amplified factory audio systems. It retains JBL and JBL Synthesis amplified audio systems with real-time and programmable speaker fade function.
Note: Aftermarket radio features such as High Pass Filters (crossovers), DSP or "Network Mode" will interfere with proper fader function. In order for the RP4.2-TY11's fader function to work, the audio from the aftermarket radio's output must match so it can compare the front and rear audio levels and determine the proper fader setting for the factory amplifier.
Programmable SWC: The interface comes pre-programmed for all of the vehicle's factory SWC functions and does not require programming, unless you wish to re-assign the SWC functions to different buttons or create secondary functions. The SWC functions can be easily programmed; see default SWC button assignments in the included user manual. The interface retains programming even if your vehicle's battery is disconnected.
Note: The SWC harness contains a Blue/Yellow wire and a 3.5mm connector. You will only use one of the connectors, based on your type of aftermarket radio. The Blue/Yellow wire supports Kenwood and newer JVC receivers. The 3.5mm jack supports Alpine, Jensen, Older JVC, Clarion, Pioneer, Sony, and Dual radios. Not compatible with Soundstream head units.
Factory Aux Input Retention: The PAC RadioPRO RP4.2-TY11 radio replacement interface module retains your vehicle's factory 3.5mm auxiliary input. Your aftermarket stereo must be equipped with a rear-panel Aux input (RCA-to-3.5mm adapter may be required).
+12V/10A Accessory Output: In many Toyota/Scion/Lexus vehicles, there is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. PAC's RP4.2-TY11 is designed to provide a 12V/10A switched accessory output (red wire).
Navigation Outputs: The PAC radio replacement interface provides wired outputs for navigation radio installation; including a VSS (vehicle speed sense), Parking Brake, and a Reverse Gear output to make installing an aftermarket navigation head unit simpler and less time consuming.
Note: Navigation outputs not retained by all vehicles.
Retains Factory Info Display: The PAC RadioPRO RP4.2-TY11 radio replacement interface module retains the factory info display (when applicable). Make sure the interface module has the latest firmware version installed.
Optional Factory USB & Backup Camera Harnesses: You are also able to retain your vehicle's factory USB input and backup camera in select vehicles with an optional harness: CAM-TY11 or CAM-TY12 (retains backup camera), or AX-TOYUSB or AX-TOYUSB-2 (retains USB input).
