Hi! I am new here and I just got a 2015 Mirage G4 (51,000Kms mileage) with an AVT CNE6515-N head unit. I got the model # from the internet after trying to find out how to adjust the time and date of the head unit. It is currently at year 2003. I was able to go to the settings menu but the date and time options are grayed out so I could't set them correctly. Please help me. Thank in advance.
