Mr. Fredrik, I noticed that you just joined the Hyundai Forums 1 day ago. Welcome to the Hyundai Forums.
You have selected a great android unit. However, I found out just like you that these units claim that they are plug n play but they really are not. However, once they are setup and configured correctly they are amazing. I am assuming they have provided you with instructions on the installation.
Few questions need to be answered.
The original head unit is it an OEM Hyundai unit or is it aftermarket?
The amplifier you mentioned is not JBL or Infinity. I looked it up and it comes up as a 2012 Santa Fe amplifier. Maybe they might used it for later years.
Now the seller should offer different harnesses one without factory amplifier and one with factory amplifier. Make sure you confirm that they sent you the correct harness.
When you connect the harness make sure it plugged in very firmly and listen for the click.
Then from the harness make sure that your canbus is firmly connected and plugged into the right spot on the back of the unit.
Plug in your USB connector to the right port on the back.
There should be another cable with the audio inputs and outputs. Make sure you have the cable plugged into the right port at the back.
Then make sure to plug in FL OUT to FL IN and FR OUT to FR IN.
The unit may also need to be setup by region, so please ask them how to get into their engineering settings and configure it for Europe. Mine was setup for China and needed to configured for North America.
Also, make sure they walk you through setting up your canbus as mine was set for a different make and model. Once we configured it for Sonata 8th Gen everything started working. Yours may need to be set to Sonata 8th Gen or ix35/45. Not sure but please confirm with the seller. They need to consult their distributor.
Not sure if your harness is the same but here is a diagram that was provided to me. View attachment 445617
RCA RED and WHITE GETS CONNECTED TO YOUR AMPLIFIER. Your unit should have another cable that has all the inputs and outputs.

Only one connection you will have to make and that is FL (White) to FL (White) and FR (Red) to FR (Red).
The android unit sends the audio to amplifier which then disperses it to all speakers. you will have no control using fade or balance.
Please make sure your antenna cable is plugged in.
Please try that and report back. Steering wheels control is another issue. There is a pink wire with a clip try unclipping that and leaving it disconnected and then retest steering wheel controls.
Hi 2XPLICIT, thanks for posting the review and pics. Do you have a picture of the 12-volt to 6-volt Step-Down Converter connection?
