What can one do once in this mode?

 

That I cannot say - I have yet to find any instructions about that. But I would definately recommend caution in changing anything

Someone got YouTube to work on the Elantra sport with the 8" display.

Remember these things runs a very old version of Android as the one from the ES ran on Android kitkat but I'm not sure about the new ones. And I'm sure that's how dealerships update these non navigation ones anyways.

1)Setup / General /SW Info
2)In the black space beside the update button..
3)On the left side, tap 5 times (near top left corner of black area)
4)On the right side, tap once (near top right corner of black area)
5)When prompted for pin, enter 2400

Thanks for the tip

 

I should have took pics and posted them here. The engineering mode on the CN7 is much more refined and the scroll bar reminds me of windows 98. Now one thing I'm curious about is the USB to update.... It has to be that one USB port that's used for charging and wired Android auto and carplay to update I'm assuming? We need a tech nerd to confirm if true. It would definitely be cool if someone made a custom ROM for these vehicles. I would love a very simple material design right about now.

 

What method did you use to access engineering mode?

 

Here's what's available in engineering mode so far. You can tap into each option shown but I'd have to take so many pictures.

 

Please sir, how i can open engineering mode in my elentra 2024

 

According to Google Translate, that Korean text is "Screen Brightness".

 

That's it? I was expecting some secret sauce. Not some screen brightness option in Korean language but whatever. Thanks for that though I did think it was gonna change the language to Korean system wide If I tapped that.

 

Something I did find useful in here was to disable the battery discharge notification (which bugs you every minute or so when you are listening to the radio with the engine off).

Discharge warning off: it's under module info/system setting

 

I wonder if you can hack the car's settings, particularly to set the Brake Hold and the drive mode (to Sport) to default to ON.

 

That's probably something in the ecu that'll have to be changed but nice username lol. Made me feel like I'm on reddit for a sec.

 

FYI, I did the April 2022 update to my head unit, and now the password is no longer "2400". Nor is it the current time.

 

Eng mode code: 3802
Variant coding code: 1200

 

You are awesome thank you.

 

I did an update 10/22
Someone has the password
3802 no longer works
LOL

 

Update, Jan-2023

Eng Mode code: 26031236
CPU Variant code: 23060663

 

Thank you sir!

 

Thank you @agmonm for posting the updated codes!

Just wanted to share my results with the forum....

I updated my '22 Elantra SEL to the latest firmware today, but still really wanted to figure out if I could change the CPU Variant to get Wired CarPlay instead of Wireless (sound quality is huge for me and I hated getting annoying drop outs from random interference) - it worked great by switching to CPU Variant 01! Note that Variant 01 does disable the wireless CarPlay and Android Auto functionality, but that does not bother me at all.

Just glad to have a functional audio system that doesn't drop to bluetooth audio frequently enough to be a bother anymore. I don't even plan on pairing with bluetooth again - just not worth it since I have the wired CarPlay now!

 

Hello,

I'm interested in getting wired carplay also in my kona but i have a few questions.

What does it reset when you change the variant - Just the display settings or other info as well (mileage, fuel consumption statistics, service date, etc)

Also any of them can be selected and revert back to any other or there might be one that will brick it?

Thanks
