Hello, my 2012 Hyundai i30's radio / main infotainment system has been playing up in wet / cold weather for a while where it would boot to Hyundai welcome screen only turning last function, like radio, with on/off and volume available only. No way to change a station, no touch control menu etc... This used to happen occasionally but now it is stuck on all the time for over a month. Also, the rear parking markings going as part of that while cam image itself still turns on and working when in reverse.
Tried car battery switch off for 30 minutes and back on to no avail.
I used to think it was some built-in in damp protection (I live on a large island so yes, it is damp here a lot
but not sure anymore as it no longer getting to work normally even on sunny days.
Any ideas how to troubleshoot/ fix it and what could it be causing that please?
