I have a 4 series 20d 2018 and all of a sudden the sat nav screen keeps blacking out.

I do a quick software reboot with the mode and radio button and the sat nav works for about 3 mins then blacks out repeated this about 5 or 6 times and still blacks out everything else on the display is fine I would appreciate some help please thanks

Could be a loose connection between the screen and the head unit. I'd take it apart and recede the cable to see if that helps.

Either the screen or the head unit is going bad.
