try resetting the infotainment system. With the car turned on, press the home button lever down and hold, the screen will go blank but keep holding down until you see the mg logo reappear, this will take 20 -30 seconds, this worked for me with sat nav issue, where it freezes at the start location. its the good old saying "Have you tried turning it off and on again"You haven't fitted a dashcam or led lights anything new to the car recently have you ?
