The tuner is set to PAL then. You will have to read the instructions and go step by step and hope it changes when you get to the right menu. Or you can plug it into a TV in side your home and go through the menu till you find the NTSC menu and press it. Then it will make the TV in the home look strange then take it back to your car and plug it in.
Ive been able to go through the menu with the same screen with luck
