I purchased a new Hyundai i30 Active X a few months ago, about a few weeks later when I turned on the ignition the screen where the Hyundai icon/radio is situated on dashboard goes blank/black.  I switch it of for 10 seconds turn it on all is good. Have no idea why this is happening.  Have mentioned this to the service centre when I returned it for its first service and they found nothing wrong.
It has happened on and a few times since end of March 2016. Does anyone have a similar experience to this? This is driving me nuts. I have contacted the dealer but waiting for response.
