RadioPRO RP4.2-HY12 Quick Start Manual

Introduction & Features
The RP4.2-HY12 interface allows the replacement of a factory radio in the Hyundai Veloster. Using this interface will
retain factory features such as: steering wheel controls (SWC), secondary screens, reverse camera and factory SPDIF
audio amplifier (seperate part required, part # RPA-SPDIF) whenever the original radio is removed. Use of this interface
also allows you to program two radio functions to each SWC button by using short press long press dual command
functionality. The RP4.2-HY12 also provides data bus driven outputs such as vehicle speed sense (VSS), illumination,
reverse trigger and parking brake.

Important Notes

1. Does not retain Blue Link. You must use the RP5.2-HY12 to retain Blue Link.
2. The AUX connection in the RP4 harness will only provide sound if the aftermarket radio has a USB port. This is because the
USB port provides the power to make the factory USB/AUX port work. If you have connected the USB plug to your aftermarket
radio and it is still inoperable, this means that the aftermarket radio's USB port is not supplying enough current.
3. When using the RPA-SPDIF in factory amplified vehicles, you can adjust factory amplifier settings such as Bass, Mid, Treble,
Fader, Balance and Gain with the RadioPRO app found at www.pac-audio.com. Please refer to page 6 for detailed instructions
on the app and the functionality of this wire.
4. In vehicles equipped with auto climate controls, you will lose the fan mode, fan speed, auto status and temperature display.
