PAC SRK-JW18EH - User Manual

The SRK-JW18EH is a comprehensive radio replacement kit designed for select Jeep Wrangler JL and Jeep Gladiator JT vehicles. This kit integrates climate control retention and includes all necessary modules and cables to maintain essential factory system features such as steering wheel-mounted radio controls, the factory reverse camera, existing USB ports, and AM/FM reception.

Function Description:

The primary function of the SRK-JW18EH is to facilitate the installation of a Stinger HEIGH10™ radio while preserving and enhancing vehicle functionalities. Through data integration with the vehicle, the kit enables the retention and addition of several features:

Vehicle Performance Gauges and Information: Allows the new radio to display critical vehicle performance data.
Climate Controls: Ensures full functionality of the vehicle's climate control system through the new radio interface.
Vehicle Settings: Retains access to various vehicle settings that were previously managed by the factory radio.
Factory Amplifier Control: Maintains control over the vehicle's original amplifier, if equipped.
Forced Camera Activation: Provides the ability to manually activate the factory camera.

The kit is designed for a plug-and-play installation, minimizing the need for cutting or splicing wires, which simplifies the process. Simplified installation and setup menus allow for direct programming of camera triggers, steering wheel controls, and other settings for both the Stinger HEIGH10™ radio and the CH4A-JW18 interface module.

Important Usage Notes:

USB Port Functionality: When properly connected, the USB port inside the center console will support Apple CarPlay/Android Auto. Other USB ports will function for USB thumb drives and charging only.
Firmware Updates: It is crucial to ensure that the CH4A-JW18, PL1, and RPA-HD1 modules are updated to the latest firmware version before installation. Instructions for firmware updates are provided in the manual.
HDMI Streaming Device: When connecting an HDMI streaming device to the RPA-HD1, an HDMI extension cable should be used to position the device away from the module, ideally in the glove box, to ensure proper functionality and prevent module malfunction.
Chime Speaker: Installation of the chime speaker is only required in vehicles equipped with safety group features.
