Product Research


USB/Aux Adapter: The iDatalink ACC-USB-HK1 is a USB/Aux adapter for select 2010-2019 Hyundai & Kia vehicles. The ACC-USB-HK1 replaces the factory Media Hub circuit board in the center console of your compatible Hyundai or Kia vehicle, so that you can retain your vehicle's factory USB port and Aux input when replacing the factory radio with an aftermarket head unit that features a rear-panel USB port and rear-panel Aux input.

  • The ACC-USB-HK1 can be used with or without the Maestro RR/RR2 radio replacement interface module and vehicle specific harness (both sold separately). See Installation Guide for further instructions.
  • This USB/Aux adapter will work with Apple CarPlay or Android Auto, except if your vehicle has multiple USB ports or if your new aftermarket radio doesn't have a high-amperage charging port (1.5A or greater).

Do I need this to use the android auto feature?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.

I read a review that stated that this does not work with Android auto or Apple carplay, if true, doesn't this defeat the purpose of buying it?

It does work, I do get random disconnects from Android auto. But from reading this seems to be more of a problem with Android Auto. I would recommend replacing the USB cable that goes from this to back of the head unit to try and mitigate some of the disconnects.

Im interested on buying the iDatalink uHK1 Adapter for Hyundai to retain the factory usb/aux, but why do I have to connect it to the vehicle original harness? if this one got disabled when I upgraded my stereo
[ Miguel  Sep 03, 2021 ]

But when Hyundai factory stereos are upgraded to an aftermarket stereo the car doesn't send any power through the factory harness. So how can it be mandatory if no power is running through the harness. The reason for it is that the factory stereo sends the signal for the harness to work and have power, but removing the factory radio disables it. Is there any technical reason to have it connected?
[ Miguel  Sep 04, 2021 ]
It needs to be connected to the factory harness for power. If you don't connect it to the factory harness, the ports will not work.
[ ZACHARY  Sep 03, 2021 ]
If I'm not using the T-Harness do I still need to plug the HK1 to the vehicle harness? If so, how am I supposed to connect it if I'm using a Crux interface? I have a Kia Rio 2014 for clarification.

I had bad luck getting mine to work correctly on the Kia Soul. I was only able to get the data transfer to work, but no charging.
[ KENNETH  Sep 01, 2021 ]
I just bought a used 2011 Hyundai Santa Fe, i am installing the pioneer AVH 4500NEX and am curious if this adapter for the factory usb will allow me to use Apple Car Play in the car or do I need a different USB extentsion?

My application for this harness is a 2015Kia Soul+. This particular harness did not work for my application due to incompatibility. Your Santa Fe may be different and compatible. Good luck and have fun with your install.
[ Cesar  Jul 18, 2021 ]
The adapter works by replacing the circuit board in your factor USB/Aux media input with this one. This one then plugs into your head unit via USB, effectively just extending the USB from the head unit into the factory AUX. The 4500 should come with a pretty heft USB cable that you can run from the head unit to this adapter iirc
