I have no clock time just shows "--:--". In settings the date/time icon is greyed out and I can't access it. I know there's a TSB (5NP-N5K9P-01) out there for this but is there a DIY solution to this. I really am pissed at Hyundai and don't want to deal with them if I don't have to. 2018 Value Edition BTW. Thanks.
