Default HELP! Ac and Nav Stopped working

So just yesterday my nav and ac were both working. Then when I went to work this morning my screen didn’t pop up and my ac buttons weren’t working. I could still see my clock and radio still works. Any suggestions ?!


Thanks

Did you drive the car after that?

Check fuses.
Do the battery test.
If battery is ok then check if it is holding charge. Culprit could be alternator.

I carry compact portable jump starter in my car it has paid for itself this year when I had alternator and battery issues.
