The link for the updater..
https://update.hyundai.com/EU/E1/Main
Download the updater, select you model Kona ev 2020 etc. You need a 32gb memory stick. Once downloaded, stick it in the usb by the wireless charger and Bob’s your uncle, car does the rest, if the software on the stick is newer than on the car it will let you update.
They tend to make some good improvements every so often, but then also chuck the odd bug in that gets sorted on the next update…
If you check the updater regularly it won’t download the software unless the version on the website is newer than on the usb stick.
Have fun.
P.S
Love mine, most I’ve done in one charge is about 330 miles, car was saying 350 miles with climate off, but I drove in normal with climate on. That included about 10 miles on restricted power and then about 3 miles on 0% battery…but it got me home…never had a doubt!
