Features

Vehicle Compatibility: The PAC RadioPro4 RP4.2-HY11 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.
  • The PAC RPA-SPDIF (541RPSPDIF, sold separately) is needed in vehicles equipped with a factory amplified audio system.

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-HY11 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-HY11 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. 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-HY11 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.

  • Red/White wire output behavior
  • Aftermarket radio Parking Brake Sequencing
  • Update Product Firmware
  • Read Firmware/Hardware Versions
  • Access Product User Manuals
Note: The interface must be connected to the vehicle and your Windows laptop when using the RadioPRO App.

A
My car has factory Steering Wheel control, a backup camera, a front AUX Jack and USB Port etc.. With out this, you will lose all of those! Plain and simple, you will have to butcher the factory wiring, and get your hands on a wiring diagram for your specific model and radio to figure out what goes where... Thanks, but no thanks.. I have used these in many installs and it is easily tucked away and keeps your car working the way you are used to but with the upgrade to the radio. [ John  Apr 20, 2018 ]
