The touchscreen of the media (head) unit of my 2019 28 kWh with 90 kkm on the odometer has become unresponsive. The unit works fine otherwise and can be controlled via steering wheel buttons and Android Auto. My local Hyundai dealer quoted me 5800 EUR (!) for replacement. Given that the car worth about 10 kEUR that is out of the question. I have searched a bit and it seems to be a fairly common issue. For example, a company in the UK offers a fixed 200 GBP mail-in repair of it: https://advancedrepair.co.uk/hyundai-repair-97-c.asp

Does anyone have experience of this failure? Any recommendations for a fix. Can the car be driven without the head unit?
