and press the SRC button to turn the unit back on, then turn it
off again to make it close properly.
• Do not try to press the buttons on the control panel as the
faceplate is moving, as excessive force may damage the unit.
• During the forced closing of the unit (i.e., having the unit left
closed whilst ignition is turned on), the faceplate will not open
no matter how often the ignition is turned on or off.
You can prevent tampering of the unit when letting someone
else drive your car by keeping it closed this way.
To cancell the forced closing of unit and open control panel:
Press the left part at the upper side of the faceplate.
The faceplate will open and show the control panel.
