About the PAC RP4.2-HY11A Wiring Interface

Upgrade the radio in your Hyundai

Installing a new car stereo can often mean losing your vehicle's steering wheel audio controls and other factory features. PAC's RP4.2-HY11A wiring interface solves this problem, allowing you to install a new receiver in your Hyundai while retaining your steering wheel controls, factory amplifier, aux input, backup cam, and USB port. The interface also supplies the connections you need to install a navigation receiver. 

Upgrade the radio in your Hyundai

Installing a new car stereo can often mean losing your vehicle's steering wheel audio controls and other factory features. PAC's RP4.2-HY11A wiring interface solves this problem, allowing you to install a new receiver in your Hyundai while retaining your steering wheel controls, factory amplifier, aux input, backup cam, and USB port. The interface also supplies the connections you need to install a navigation receiver. 

DAC converter included

The package also includes PAC's RPA-SPDIF module, which converts the analog audio signal from an aftermarket radio to a digital signal that's compatible with your Hyundai's amp. The module's premium Wolfson digital-to-analog (DAC) converter ensures high-quality sound reproduction. An adjustable gain control lets you match your new car stereo's signal to the Hyundai amp, while power and clipping LEDs allow you to monitor the module's performance. You'll lose fader control with your new radio, but PAC's RadioPro PC application enables you to make fader adjustments from your front to rear speakers with a Windows-based laptop.

Important Notes: This wiring interface will only retain steering wheel audio controls with car stereos made by Alpine, JVC, Kenwood, Clarion, Pioneer, Sony, Fusion, Advent, Boyo, Dual, Lightning Audio, Rockford Fosgate, and Visteon. The retained USB port is not compatible with Apple CarPlay or Android Auto.

Installation Notes: In the 2013-15 Genesis Coupe and 2011-14 Sonata, you will lose the ability to set the factory clock, and your vehicle's external screen will power up and display "Aux." In the 2013-15 Azera, your vehicle's external screen will power up and display "Hyundai" (climate control display will be retained).

Features

Vehicle Compatibility: The PAC RadioPro4 RP4.2-HY11A allows you to replace the factory radio with an aftermarket head unit, while retaining a variety of factory equipped features in select 2011-2015 Hyundai vehicles.

Make Model Year
Hyundai Accent 2011-2015
Azera 2013-2015
Elantra 2011-2015
Genesis Coupe 2013-2015
Santa Fe 2013-2015
Sonata 2011-2015
Tucson 2012-2015

Vehicle Notes:

  • In the 2013-2015 Genesis Coupe and 2011-2014 Sonata, the factory external screen will power up and display "Aux", plus you will lose the ability to set the factory clock.
  • In the 2013-2015 Azera, the factory external screen will power up and display "Hyundai" (The climate control display will be retained).
  • Vehicles equipped with factory navigation are not compatible.
  • Does not retain Blue Link.

Retained Factory Amplifier: The PAC RadioPro4 RP4.2-HY11A retains your vehicle's factory amplifier and subwoofer via the included amplifier retention module. Fader capability can be retained via a PC application.

Built-In Pre-Programmed 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. The SWC functions can be easily programmed (see owner's manual). The interface retains programming even if your vehicle's battery is disconnected. 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.

  • Blue/Yellow Wire: The Blue/Yellow wire supports Kenwood, newer JVC, and Blaupunkt aftermarket head units.
  • 3.5mm Jack: The 3.5mm jack supports Alpine, Jensen, Older JVC, Clarion, Pioneer, Sony, and Dual radios.
Note: Not compatible with Soundstream head units.

Retains Factory Aux Input: The PAC RadioPro4 RP4.2-HY11A features a set of stereo RCA jacks which plug into your aftermarket head unit's rear-panel Aux input in order to retain your vehicle's factory auxiliary input. A RCA-to-3.5mm adapter (sold separately) may be required depending on your aftermarket radio's aux input connection.

Factory Retained USB Port: The RadioPro4 RP4.2-HY11A will retain your vehicle's factory USB port using the integrated USB cable which plugs into your aftermarket head unit's rear-panel USB input.

Note: The retained factory USB port is not compatible with Apple CarPlay or Android Auto.

Factory Backup Camera Retention: The interface also retains your vehicle's factory back-up camera through its composite video jack that plugs into the camera input on the back of your new aftermarket stereo.

10A Accessory Output: There is no 12-volt accessory wire in the factory harness, so PAC's RP4.2-HY11A provides a data controlled 12V/10A switched accessory output (red wire). This prevents you from having to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio.

Navigation Outputs: The PAC radio replacement interface also provides 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.

Programmable 12V Output: The red/white wire on the interface can be programmed via the RadioPRO app to do a pulsed or latched 12v output which can then be assigned to any of the vehicle's factory SWC buttons. When assigned, the factory SWC button will activate the pulsed or latched output to control external accessories.
