Issues Updating 2018 Ioniq Hybrid Navigation Software

[Ilovebooks001]

hello, everyone!

I want to update my 2018 Ioniq Hybrid Blue, but I face some software problems.
After I downloaded the nav updater on a thumb drive and then put it in, the car is playing random .wav files. Like what the duck?
I need help, please. After installation using proper Gen4, I got these files:
- text.info,
- update,
- vr,
- 2017_18_Ioniq_Hybrid_USA.ver,
- HKMC_Navi.

I also get this message: "Please select the Update folder".

I can't quit the car because I love it, but the nav software firmware is close to 8 years old. Please help!
Thanks in advance!

Are the files you mentioned inside the Update folder?
If yes, then I think it might be the USD format. Is it formatted to FAT32?

Try these.
