The colour of the display of my car stereo changes every 10 seconds. How can I switch this setting off?

Simply switch off your CD Tuner and hold down the ‘5’ button for a few seconds.

If your CD Tuner doesn’t have a ‘5’ button:

• Switch off your CD Tuner and hold down the ‘Source’ button for a few seconds. Turn the dial until ‘Reverse’ is visible. Turn ‘Off ‘to switch the colour change off (and of course ‘On’ to activate it).
• After you have switched off your device, press the BAND button shortly while the contact is on ACC or ON. This cancels or activates the reverse mode.
