Frequently Asked Questions - RPK4-CH4103 PAC

Will the RPK4-CH4103 work with my 2016 Jeep Grand Cherokee?

Yes, the RPK4-CH4103 is designed for 2014-2020 Jeep Grand Cherokee. However, installation steps differ between 2014-2017 and 2018+ models. For 2014-2017, you may need to relocate the AC/heater control module if depth is an issue.

My steering wheel controls are not working. What should I check?

First, verify that the DIP switches on the RP4.2-CH4103 interface are set correctly for your aftermarket radio brand (see page 9 of manual). Next, ensure the SWC output (3.5mm jack or wired connection) is properly connected to your radio. If still not working, try resetting the interface by holding the programming button until LED flashes red.

How do I retain the factory reverse camera?

Use the included RPA-16P1V harness. Connect the Male Yellow RCA (Video Output) to your aftermarket radio's reverse camera input, and the Female Yellow RCA (Video Input) to the factory reverse camera's video output. Connect the Red and Black power wires to the aftermarket camera if needed, or insulate if not used.

Can I add more cameras besides the reverse camera?

Yes, with the optional PAC RPA-16P5V harness (sold separately), you can connect up to 5 cameras. The LCD screen allows switching and automatic triggers. Camera 1 is permanently set as reverse; cameras 2-5 can be configured as front, left, right, etc. through the settings menu.

The climate control fan speed is low and unresponsive after installation. What's wrong?

The vehicle needs a sleep cycle. Turn off the ignition, close all doors, lock the vehicle with the key fob, and wait at least 10 minutes. After that, start the vehicle and check climate control again. If issue persists, try resetting the interface or disconnecting/reconnecting the LCD display harness.

How do I program the four hard buttons below the LCD screen?

Go to the Options screen on the LCD, then select Button Settings. Choose the button (1-4) you want to program. You can assign a climate control function (e.g., Max A/C, Sync), a camera activation (e.g., Camera 2), or a screen shortcut (e.g., Gauges). Press the desired option to confirm.

Do I need to cut the dashboard for installation?

For 2014-2017 models, you may need to trim the top of the radio opening (9/16" cut) to allow the mounting shroud to fit. For 2018+ models, no cutting is required. Also, on 2014-2017 models, relocation of the AC/heater control module may be necessary if the aftermarket radio is deep.

How do I update the firmware of the RPK4-CH4103?

Download the RadioPRO PC app from PAC's website. Connect the RP4.2-CH4103 interface module to your computer via USB. In the app, select 'Firmware' > 'Update Firmware' and browse to the downloaded file. The LCD bezel can also be updated via its USB port using a USB drive (see manual for details).

Can I adjust the volume of the parking sensor chimes?

Yes, through the Advanced Settings menu on the LCD. You can choose which chimes (front/rear) are sent to the external speaker and adjust the chime speaker volume by sliding the bar up or down.

What does the 'Real Time Fade' option do in the factory amplifier settings?

When Real Time Fade is On, fading is controlled by the aftermarket radio's fader. When Off, fading is only adjustable from the RPK4-CH4103 menu. This allows you to choose whether the fader follows the radio or is set independently.

USER MANUAL RPK4-CH4103 PAC

Introduction and Features

The RPK4-CH4103 is a complete radio replacement kit with integrated climate control retention for the 2014-2020 Jeep Grand Cherokee. All modules and cables are included to retain important features of the factory system including: steering wheel-mounted radio controls, factory reverse camera, and AM/FM reception.

A secondary 5.2" LCD screen is added for additional vehicle features and controls including: vehicle performance gauges and information, climate controls, vehicle settings, factory amplifier control, and forced camera activation. Simplified installation and setup menus allow direct programming of camera triggers, steering wheel controls, and other settings of the kit and RP4.2-CH4103 interface. Features provided by the LCD screen will vary based on the vehicle features. See Important Notes (next section) for additional information.

Four hard buttons added to the radio dash bezel (below the 5.2" LCD screen) allow the user to set presets to control functions including: specific climate controls, forced camera activation, and LCD screen controls. Options for hard buttons will vary based on vehicle features and which cameras are installed.

Button inserts and seven button openings on the radio dash bezel allow for retention of functions that would typically be lost when replacing the factory radio.

Some advanced features require additional accessories (sold separately).

Important Notes

We recommend reading this manual thoroughly to familiarize yourself with the entire process prior to beginning the installation.

1. In vehicles equipped with parking sensors, you must use the included external speaker in order to continue hearing parking sensor chimes. If the vehicle has a factory amplified system and parking sensors, the speaker is not necessary unless the factory amplifier is no longer being used. In cases where the factory amplifier and aftermarket amplifier are being used (for example, using an aftermarket amplifier for the front speakers and using the factory amplifier for the rear speakers), the RPK4-CH4103 allows the chime output to the external speaker to be set to the channels that are being driven off of the aftermarket amplifier.
2. If you are adding additional cameras, PAC part number RPA-16P5V (sold separately) must be used to connect up to 5 total cameras.
3. It is very important that the vehicle's accessory buttons be programmed and tested right away. If they do not operate, it is likely because the incorrect CAN wire connections are being used.

Vehicle Accessories Buttons:

In 2018+ vehicles, the CAN connections must be made at the vehicle's star connector (see page 10 for details). Failure to do so will cause the vehicle's accessory buttons to not operate and may cause the vehicle's battery to drain.

1. In newer (2018+) vehicles, the factory amplifier may not work or the audio level will be low until the ignition is cycled. Make sure the aftermarket radio's volume level is turned down prior to cycling the ignition to prevent excess volume after the ignition cycle!
2. Only in 2014 Grand Cherokee: All vehicle settings options will be listed in the vehicle settings menu, including vehicle settings that are not available for your vehicle. The only settings options that can be changed and saved, are options that were available through the factory radio.

Components

Tools needed for installation: Phillips head screwdriver, pick tool or small flathead screwdriver, 7mm socket, ratchet, T20 torx screwdriver, plastic panel removal tool (example - PAC part number TL-PRY2), and an airsaw or hacksaw for sub-dash modification (only required for 2014–2018 applications).

The vents must be removed from the factory dash panel for reuse with the RPK4-CH4103. To remove the vents, use a pick tool or small flathead screwdriver to release the bottom vent tabs, and slightly pull the bottom of the vent away from the dash panel. Do the same with the side vent tabs. With the bottom and side tabs released, release the locking tabs on the top vent as you pull the vent straight out and away from the dash panel. The factory dash panel can now be stored away for use when it is time to reinstall the factory radio.

Part Three: Installing the New Dash Panel

Installing Vehicle Accessories Buttons and Auto Climate Button

Step 1

The RPK4-CH4103 comes with a "Blank" and an "Auto" button insert for the fan speed knob. The Grand Cherokee always comes with the auto HVAC function, so install the insert that says "Auto". Be sure to line up the light pipe with the hole in the kit, and then push the button into place.

Step 2

Depending on the accessories installed on the vehicle, there may be up to 7 functioning buttons below the climate controls. Only the options available on the factory dash panel will operate with the RPK4-CH4103. Inserting buttons with icons that do not match the factory buttons will not add features to the vehicle.

Step 3

Sort through the included RPK4-CH4103 loose buttons and set aside the ones that match the buttons on the factory dash panel and a blank button / buttons (when necessary) for a total of 7 buttons that will be installed into the new dash panel. The leftover buttons will not be used.

Step 4

The buttons will be programmed later (see page 16), so their arrangement in the new dash panel is a matter of customer preference. The top of the blank is easily noted by the line on the side. Loosely slide the buttons into the desired opening, but make sure you are satisfied with the positions prior to seating them fully into the kit. The buttons are difficult to remove once they are fully seated.

Step 4

Release the dash trim that surrounds the base of the steering column by pulling the trim away from the dash. With the trim pulled back, there is space to slide your hand into the dash to route the MQS4PT-36 harness and to plug it into the star connectors. Route the MQS4PT-36 harness to the star connectors on the left-most side of the dash. Make sure to route the cable to where it does not interfere with any moving parts (brakes, accelerator, steering column).

Step 5

Plug the MQS4PT-36 male Green and White connectors into the appropriate ports on the star blocks. The Green connector from the MQS4PT-36 plugs into a port in the White star block, and the White connector from the MQS4PT-36 plugs into a port in the Green star block. If the star block does not have an open port, remove one of the existing connectors, plug it into the female connector from the MQS4PT-36 and plug the male from the MQS4PT-36 into the now open port on the star block.

Step 6

Locate the Black 4-Pin mated connectors in the RP4.2-CH4103 harness. Unplug the connectors, and attach the Black 4-Pin male connector from the MQS4PT-36 into the Black 4-Pin female connector that goes to the White JST connector. The remaining Black male 4-Pin connector in the RP4.2-CH4103 harness will no longer be used.

Wiring Connections (Section B)

1. Connect Interface Connector 3 to either the amplified output connector if retaining the factory amp or to the non-amplified audio output connector if there is no factory amplifier.

2. Connect one end of the supplied LCD Display harness into the LCD Display Port on the RP4.2-CH4103 interface module, and ensure that it will be accessible when installing the radio dash bezel.

3. Set the DIP Switches on the side of the interface according to the chart on page 9.

3. If you are retaining or installing cameras, connect the RPA-16Pxx harness into the Camera Input / Output (Connector 3) on the back of the radio dash bezel (see Fig. 1).
4. OPTIONAL: To update firmware with minimal effort and without accessing the back of the radio dash bezel, a USB extension cable, PAC part USBDMA3 (sold separately), can be connected into the 5.2" Display USB port (Connector 4) on the back of the radio dash bezel (see Fig. 1) and run to a location that allows for easy access (glove box, tucked under an interior panel, etc.).
5. Once the radio dash bezel has been connected, the LEDs for the illumination of the four hard buttons on the kit (below the radio dash bezel's LCD display) will illuminate momentarily and then start flashing. This indicates the system is initializing. Next, the LEDs will turn off and then the RadioPRO splash screen will appear on the LCD. The initialization sequence can take up to 2 minutes on initial powerup. Once the LCD screen comes on, you can proceed to the setup and testing section on the next page.

Using Multiple Cameras

With the addition of the optional RPA-16P5V harness, the RPK4-CH4103 supports the display and control of up to 5 cameras. The RPA-16P5V replaces the RPA-16P1V camera harness that is included with the RPK4-CH4103.

Additional cameras can be connected to any of the 4 separate video inputs (video input 1 is reserved for the reverse camera). Camera input and control are adjustable through the settings menu on the LCD display on the dash bezel. The provided power and ground connections are active when the vehicle is on. Use these leads to power your aftermarket camera(s) (up to 800mA total). If the cameras require more than 800mA, please use an external relay. See page 17 for setup and operation.

Setup and Testing (cont.)

Vehicle Accessories Buttons Setup

Because the vehicle accessories buttons that are used vary from vehicle to vehicle, the accessories buttons must be configured to the position in which they are installed. Some vehicles will have fewer installed accessories, so instead of a button there will be a blank installed. Configuring a button that was not present on the factory dash panel will not add features to the vehicle.

Step 1

Open Installer Settings

Step 3

If the vehicle is equipped with the button shown, press that button on new dash panel. If not equipped, press "I Do Not Have This Button". Once the button is programmed, a different button will be displayed. Continue this process until the verify configuration screen is displayed.

Step 2
Open the Buttons Setup Wizard

Step 4

Verify that the buttons are correct on the display, and match the buttons and button positions on the new dash panel. If the layout matches, press "Looks good" to complete the vehicle accessories buttons setup. If it does not match, press "Go back" to perform the setup again.

Camera Setup

The camera settings menu is used to set up which cameras are installed on the vehicle. When used with the PAC harness RPA-16P5V (sold separately), the RPK4-CH4103 gives you the ability for switching via the 5.2" LCD and automatic triggers for up to 5 different camera images to display on the aftermarket radio. Note: Camera 1 is permanently set as the Rear Camera and cannot be changed in the settings menu. Camera inputs 2, 3, 4 and 5 can be toggled between "None" (no camera) or the options shown in Fig. 1 below.

Note: 2 Wire Resistive radios do not have a specific default programming order and cannot be custom programmed through the RPK4-CH4103. Please refer to the owner's manual of your particular radio for programming instructions.

Custom SWC Programming

Example: To program the Track Up button to perform the Track Up function with a quick press and perform the Preset Up function when the button is pressed and held for more than 1 second, from the SWI settings menu, do the following:

Step 1
Open SWI Settings

Step 2

Touch the display on the Track Up Long Press function that is currently labeled as Not Assigned.

Setup and Testing (cont.)

Step 3
Scroll to find and press the Preset Up option.

Audio Adjustments

Custom SWC Programming Tips:

Each SWC radio function can be used only once. If you try to use a radio function that is already assigned to a button, the pre-existing button's radio function will change to "Not Assigned", and the radio function will be set to the new button. For example, if you were to try to program Volume Up to the Mode button, the Volume Up button would now be set to "Not Assigned", and the Mode button would be set to Volume Up.

If the vehicle has a factory amplifier, the 5.2" display has the ability to adjust the factory amplifier's audio settings.

Amplifier Audio Settings

Step 1
Open Factory Amplifier Settings

Step 2
Make Adjustments

Real Time Fade On = Fading from aftermarket radio Real Time Fade Off = Fading from this menu only Note: Typical Gain Setting will have the gain at or near the top.

Chime Speaker Adjustment

The chime speaker adjustment allows you to control what chimes will be sent to the RPK4-CH4103-supplied chime speaker and the volume of the chimes from the speaker. If there is no factory amplifier, or if an aftermarket amplifier is being used for the front / rear / all speakers, the chime speaker can be adjusted for that particular application. This setting will not affect the output of chimes through the factory amplifier, only what chimes (front\rear) will output through the external speaker and the volume of the chimes through the external speaker.

Step 1
Open Advanced Settings

Step 2
Adjust Chime Speaker

Front Chimes - On (Highlighted) / Off (Not Highlighted) Rear Chimes - On (Highlighted) / Off (Not Highlighted)

Chime Speaker Volume - Slide Up to Increase Slide Down to Decrease

Setup and Testing (cont.)

Hard Buttons

The four hard buttons located below the RPK4-CH4103 display give you the ability to assign a single preset to each button to control a speci c Climate Control function, force activate a speci c camera to display on the radio or control select screen settings. Once the buttons have been assigned a function, a descriptive pop-up tab above each button showing what function that button performs will be presented when the proximity sensor is alerted to your nger touching the button (this function can be toggled on / o ).

If popups are turned on in the menu: The proximity sensor within the dash bezel will display the descriptive tabs when your nger touches the buttons. When your nger is removed, the tabs will disappear.

The options that are able to be preset to the hard buttons are:

Climate Control Functions\*

• Max A/C
• Sync
• Heated Wheel
• Fan Mode

CameraFunctions\*\*

• Camera 1
• Camera 2

• Camera 3

• Camera 4

• Camera 5

Screen Shortcut Functions\*

• Climate
• Cameras
• Gauges
• Display On / O

* Climate Control Functions will vary for Single Zone and Dual Zone applications.
** The number of available cameras will vary based on how many cameras are installed and activated.

Assigning functions to the Hard Buttons

Step 1 \$tep 2

Press the Button Settings icon in the main menu

Step 3

Click on the device (Unassigned, Climate Control, Camera) operation you wish to program. In the example, we want to use the first hard button to force activate the Nanny camera, so we select the Camera option.

Touch the tab that corresponds to the hard button that you wish to assign a function to.

Step 4

In the example, because Camera 5 is the Nanny camera, we select the Camera 5 option. Repeat steps 3 and 4 for each hard button you wish to program.

Setup and Testing (cont.)

To test the functionality of the radio and RPK4-CH4103, start with the ignition off and driver's door open and then do the following:

1. Turn the ignition on. The LED on the interface will turn on, and the +12v accessory wire will turn on.
2. Verify that all RPK4-CH4103 radio dash bezel buttons operate their intended function:

a. Hazard Button
b. Climate / Defrost Buttons
c. Vehicle Accessories Buttons

1. Turn on the radio, and check volume, balance and fade.

2. If the overall volume is excessively low or high: Verify that Interface Connector 3 is connected to the appropriate output connector on the RP4.2-CH4103 module (one is for amplified audio systems, while the other is for non-amplified audio systems).

3. If the overall volume is slightly lower or higher (vehicles with a factory amplifier only): Use the factory amp gain adjustment through the RPK4-CH4103 settings menu to set it to the desired level. See page 19 for information on how to access the factory amplifier settings menu.

4. Verify that all SWC are functioning properly. See the Steering Wheel Control section (page 18-19) for radio-specific details.

5. Verify that all vehicle functions are present through the RPK4-CH4103 5.2" LCD display:

• Climate Controls
• Factory Amplifier Settings (Only applicable in vehicles with a Factory Amplifier)
• SWI Settings (If DIP Switches are set for any radio other than 2-Wire Resistive)
• Vehicle Settings
• Information Screen
- Vehicle Gauges
- Camera Control

Troubleshooting

1. On initial install, Climate Control fan speed is low and unresponsive - The vehicle needs to be sleep cycled. Turn the vehicle off, close all doors, lock the vehicle with the keyfob and let it sit for 10 minutes. After 10 minutes, start the truck and check the Climate Control functionality again.
2. If a vehicle function is not present: Reset the RP4.2-CH4103 Interface Module (see page 22). If a vehicle function is not present after a reset: With the vehicle running, disconnect and reconnect the LCD Display Harness from the back of the radio dash bezel.
3. Steering wheel controls inoperable - Verify that the DIP switches are set properly according to page 12 of this manual.
4. Reverse Camera inoperable - Verify that all reverse camera connection points are proper by reviewing the reverse camera wiring connection steps on pages 14 and 15.
