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, and the built-in 3.5mm auxiliary audio jack. The
built-in USB connection and back-up camera can also be retained in conjunction
with an optional PAC harness (sold separately).
Vehicle Compatibility: The RadioPRO 4 RP4.2-TY11 is
compatible with the following 2003-2016 Toyota, Scion, & Lexus vehicles (as of
- 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).
- Not compatible in Lexus vehicles equipped with factory navigation.
Radio Select Switch: 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. 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.
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.
Optional Factory USB & Backup Camera Harnesses: You are able to retain
your vehicle's factory USB input and backup camera in select vehicles with an optional harness from
PAC (USB-TY1, USB-TY2,
