Hi,

I bought a 10.25 unit that came off from 2021 Hyundai kona to install into my 2020 kona that has factory 7 inch unit.

the installation seems fine and everything seems to work however I don’t get any sound. Is this something to do with wiring.
Also, the new unit has an extra plug that I didn’t have for my factory unit. (See photo) not sure what that would be for.

Any help would be appreciated
New one (with extra plug)

This is a swap that is almost impossible on Hyundai/KIA vehicles. Most Car makers use one harness for all the models in their line up and leave redundant plugs in place. On the other hand Hyundai/KIA seem to use a model specific harness. Making it impossible to upgrade to the navigation unit for the models that don't have it. It has been attempted by multiple members on both forums with no success. One guy on the elantra forums spent a long time even fabricating his own harness. I don't think he was entirely successful.

Yep, with completely different wiring. Kind of a F'ed up way to do it. But hey, Hyundai can't build 75% of their engine models from blowing up on 14 to 25 of their cars. Why would standardization make sense to this company. I installed 2017 Hyundai Elantra Sport seats in my 2018 Kona and all the seat and airbag wiring is ALL different. So no airbags. I did that with an Audi and the seats just plugged right in.

yes , missing the amplifier , which is located under the front set. But its not a matter of just getting any audio amplifier.
In laymans terms. The output from your old unit, is an audio signal that goes to your speakers or a standard amplifier if you want bigger better performance.
The output from the new upgraded unit, is a digital signal that feeds to a special decoder/amplifier before feeding the speakers.
In other words , you would need Hyundai specific amplifier and then correctly configure the wiring.
I have looked into this , everything works ,sat nav, channel search. except the sound.. My biggest issue would be where to interface the volume control.
Goodluck with this. Keep us posted

Now. I'm scared I have an unbranded 10.1 electronic rotating screen unit I am planning to install in a couple days. I have purchased the kona wiring harness from Crutchfield and wired it all together finally after having it for a few weeks. Work depending on my job schedule. So hopefully I will get sound! The videos I've found basically say with the wire harness it will work. The only videos I could find of similar install on YouTube in a kona were from the Phillipines I believe. I'll update once I attempt the install. I have a kona full of mods and customs to build and install. But restaurant management and mods are definitely not good friends....

Like every reply in this forum very late. I never did. Now I got a 12.3 inch display. As of last night I have everything working except no sound like the others. Some say impossible but I've seen somr that get sound. So i dont know. I'll let you know if i get it working. So when you randomly check the forum a year later and don't need 2 year old info it will be here. Lol

Just in case someone is still looking to swap.
you will need a Rockford Fosgate dsr1, a Maestro acc-ar-spdif, a Maestro ahk3 horn-ar t-harness, an aftermarket AMP I used the Sony xms400d because of its size.
the easiest way will be to add the two pins for the Amp SPDIF high and low, the two pins for the navigation voice + and - to you radio wire harness. tap into the multimedia-can cables (high and low) then run does cable to the maestro ahk3 hrn-ar amplifier t-harness. Remove or (cut if you are comfortable soldering wires) all the speaker wires out off your radio wire harness and connect them to your AMP. Good luck!

Sorry i dont understand..can you explain detail steps?
i used the following method to get engineering mode, i could access. But not the one i want..

Engineer Mode (Full Engineering Mode) – 2 knobs

Choose Radio
In a quick sequence set the volume using left knob to level 0, then to level 7 and press the right knob, then set the volume to level 3 and press the right knob, then set the volume to level 1 and press the right knob

Is it a 10” head unit for an electric kona?
