How to change date? Wrong date maybe afert my Android Auto problems

[nolot5]

Hi

I have been using Android Auto with a brand new Galaxy S7 and a brand new California T6 MY2018 with discovery media during first week..

But suddenmy when I plugged the phone in the USB, a red screen of A.A.appears on my phone... Error 8, check hour and date in the car.

I checked hour, in the dash board, but i can't check the date, i read the owners manual, and in the discovery media setting screen I must see a field "Time/date", but it's not in mine's...

I think date it's wrong because I saved a nonamed destination in the nav, and file name is 01-20-2001 ........

Could somebody help me? Excuse my bad english please.
