Be careful not to mess things up. You have been warned!

Settings menu for QQ without SatNav:

1. Press and hold MENU while turning the volume knob clockwise or anti-clockwise for some time.
   
2. The radio display turns on and shows 'SPEAKER 0000'.
   
3. Using the ENTER knob you can cycle through several options.
   

How to actually adjust things (if you really, really want to [Tienes que estar registrado y conectado para ver esa imagen] ) is not yet known.

Press and hold the ENTER knob, will display 'DELETE ALL '
Could be this is to clear the fault log but, as you can understand, it probably isn't wise to change this to YES without knowing more about all options/settings...
