Hyundai and Kia Integration Harness

The Axxess AXDIS-HK3 data interface connects an aftermarket audio system to select 2017-Up Hyundai and Kia vehicles. It supplies a 12-volt 10-amp accessory feed and retains Retained Accessory Power. The module provides navigation outputs for parking brake, reverse and speed sense signals. Steering-wheel audio controls, factory backup camera and chimes including parking-sensor alerts remain functional.

Vehicles with Sony A2B Amplifiers

This interface is designed for models equipped with Sony A2B amplifiers and includes a built-in digital signal processor. It retains SYNC voice prompts and routes all chimes through the aftermarket amplifier or cluster with adjustable chime level. An amplifier bypass harness is included for non-amplified configurations. Buyers whose vehicle lacks the A2B architecture or who need a simple ISO harness without DSP should look at a different interface.

Radio Trim and Feature Codes

Confirm the exact model year and radio trim using the fitment notes: Android Auto or Apple CarPlay radio, navigation presence, manual climate control on the 2019 Optima, and the 2020 Santa Fe 360-camera exclusion. The module updates via Micro-B USB, so verify a USB cable and computer are available for firmware installation.

Questions about this item

Do I need a Sony A2B amplifier already installed for the AXDIS-HK3 to work?

Yes, the interface is designed specifically for Sony A2B amplifiers and includes a built-in AX-DSP-X digital signal processor that communicates over the A2B bus.

Will the AXDIS-HK3 keep my steering-wheel audio controls working on a 2018 Kia Forte with Android Auto?

The AXDIS-HK3 retains steering-wheel audio controls on listed vehicles including the 2017-2018 Forte with Android Auto and no factory navigation.

How can I confirm the AXDIS-HK3 is functioning correctly after installation?

Verify that factory chimes and SYNC voice prompts play through the aftermarket amplifier, the backup camera still operates, and steering-wheel controls respond; the Micro-B USB port also allows firmware updates if needed.
