Yes, You can turn it off and you can also lower the screen brightness. Select your CD music first and start the playing. You can still use the steering wheel audio controls when MYLINK screen is off.
Here are the steps to turn the display off.
1) Press Home Icon (Picture of a house)
2) Select SETTINGS
3) Select DISPLAY
4) Select OFF – that will turn screen black (Blank) – To turn it back on – press anywhere on the screen.
TIPS: Set the display mode to AUTOMATIC and then MYLINK will auto adjust brightness. If that fails to satisfy then lower the brightness to you desired level using the plus and minus icon in the display brightness option.
