Introduction and Features

Important Notes

The SR-TUN14HX is a complete radio replacement kit for the installation of the Stinger HORIZON10

modular radio in Toyota Tundra.

All modules, cables and adapters are included to retain important features of the factory system, including: steering wheel-mounted

radio controls, factory amplier, factory reverse camera, factory USB port and AM/FM reception. Plug & Play wiring harnesses allow

for quick and easy installation without the need to cut or splice any wiring. The display mounting panel allows mounting the 10 inch

display without modifying/cutting any part of the vehicle’s sub-dash.

1. Adjustment of the vehicle settings through the original radio’s vehicle settings menu will be disabled after installation of the new

radio. It is advised to make sure all settings are as you desire prior to removal of the original radio.

2. The RP4.2-TY11 does not retain Rear Seat Entertainment.

3. To retain SiriusXM Radio, a SXV300 Tuner is required and sold separately.

4. After installation, if you do not initially hear any audio, you may need to cycle the ignition again to initialize the factory amplier.

5. Speaker fading on factory amplied systems is only supported with the “amplied output” connection of the RP4.2-TY11.

6. When using real time fade, if the fader setting is biased more to the front or rear, as the radio turns on the sound may begin at

the default setting and then quickly transition to your custom setting.

7. Radio features such as High Pass Filters (crossovers) will interfere with proper fader function. In order for the RP4.2-TY11’s fader

function to work, the audio from the radio’s output must match so it can compare the front and rear audio levels and determine

the proper fader setting for the factory amplier.

8. If the truck is equipped with a factory 360° camera system, changing camera views using the touch screen will no longer be

available. Camera views can be changed using the steering wheel controls only.

We recommend reading this manual thoroughly to familiarize yourself

with the entire process prior to beginning the installation.

Restoring Factory Settings

Testing and Verication

RadioPRO App

Use of the RadioPRO App allows

you to do the following:

• Congure User Interface Options:

• Factory amplier settings

(Bass, Mid, Treble, Gain, Fader

and Balance)

• Real Time Fading

• Update Product Firmware

• Read Firmware/Hardware Versions

PLEASE NOTE:

The interface must be connected to the vehicle when using the following features of the Radio PRO App:

• Factory Amplier Settings

The interface does not need to be connected to the vehicle when using the following features of the Radio PRO App:

• Firmware Updates

• Reading rmware/hardware versions

1. Turn on the radio and check volume, balance and fade. If you do not hear any audio you may need to cycle the ignition to

initialize the factory amplier. If there is still no audio, reset the interface according to the procedure in the next section.

2. For JBL systems, if the overall volume is too low, use the gain adjustment on the side of the RP4.2 interface to set it to the

desired level. The best way to do this is to turn the volume on the radio to 3/4 volume, then turn the gain on the RP4.2 until

some distortion is heard, then back it down a little.

3. Verify that all SWC are functioning properly. If any of the SWC are not functioning properly you may need to reset the

interface.

4. Verify AM/FM Reception, Bluetooth, USB, Apple Carplay, Android Auto and Camera(s) are functioning correctly.

You can restore the RP4.2-TY11 interface to factory default settings by pressing and holding the programming button on the side

of the module until the status LED starts blinking red. Once the LED starts blinking red, release the button. You must release the

button while the LED is blinking red in order to perform the reset. Please note, the LED will go through two stages before it starts

blinking red. First it will blink green, then amber, then red.

This reset will restore the following settings to their factory defaults:

• SWC Mapping

• Factory Amplier Settings

• Real Time Fade will be reset to on

Infotainment/Factory Amplier Settings

The RadioPRO app will also allow you to adjust the

settings of the factory amplier. You can adjust Amp

Gain, Fader, Balance, Bass, Mid and Treble and real

time fade. When real time fade is enabled in amplied

systems, it will allow fading to be controlled directly

from the aftermarket radio. Restoring factory settings

on the module will default all values back to middle.

RadioPRO App (continued)

Firmware Updates

The RadioPRO app will also allow you to update the

interface with new rmware as it becomes available.

Please visit www.pac-audio.com or contact our tech

support department to see if there is a rmware update

for your interface.

In order to update the interface all DIP switches must be set to the down position. Connect the interface to your PC and select

“Update Firmware”. Now select “Select File”. Finally, browse to the place where you saved the le and select it. This will begin

the updating process. Once nished, disconnect the interface from the PC and set the DIP switches back according to the radio

you have installed.
