SR-TAC16H Stinger HEIGH10® Radio Replacement Kit for 2016-2021 Toyota Tacoma
This document provides installation instructions for the SR-TAC16H kit, enabling the installation of the Stinger HEIGH10® modular radio in compatible Toyota Tacoma vehicles.
Introduction and Features
The SR-TAC16H is a complete radio replacement kit for installing the Stinger HEIGH10® modular radio in Toyota Tacoma trucks equipped with either 6" or 7" factory display radios. All modules, cables, and adapters are included to retain important features of the factory system, including: steering wheel-mounted radio controls, factory amplifier, 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 or cutting any part of the vehicle's sub-dash.
Important Notes
We recommend reading this manual thoroughly to familiarize yourself with the entire process prior to beginning the installation.
- 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.
- The RP4.2-TY11 does not retain Rear Seat Entertainment.
- To retain SiriusXM Radio, a SXV300 Tuner is required and sold separately.
- After installation, if you do not initially hear any audio, you may need to cycle the ignition again to initialize the factory amplifier.
- Speaker fading on factory amplified systems is only supported with the “amplified output” connection of the RP4.2-TY11.
- 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.
- 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 amplifier.
- 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.

Testing and Verification
- Turn on the radio and check volume, balance, and fade. If no audio is heard, cycle the ignition to initialize the factory amplifier. If audio is still absent, reset the interface as described in the "Restoring Factory Settings" section.
- For JBL systems, if overall volume is too low, use the gain adjustment on the side of the RP4.2 interface. Set the gain to the desired level by turning the radio volume to 3/4, then adjusting the RP4.2 gain until slight distortion is heard, then backing it down slightly.
- Verify that all Steering Wheel Controls (SWC) are functioning properly. If any SWC are not functioning, the interface may need to be reset.
- Verify AM/FM Reception, Bluetooth, USB, Apple CarPlay, Android Auto, and Camera(s) are functioning correctly.
Restoring Factory Settings
The RP4.2-TY11 interface can be restored to factory default settings by pressing and holding the programming button on the side of the module until the status LED blinks red.
