Hi Mike, If you go into your menu (on radio panel) Personalisation Configuration will appear, press ok(on radio panel). Display Configuration will appear, press ok. Choice of units will appear, you can pick litres for fuel and kph by the arrow keys( around ok), when you have selected your units select ok on the display by using the left arrow key next to the ok button so ok is highlighted on that display panel, then press the ok button again then menu, all done. http://i2.photobucket.com/albums/y39/bobtim/panel.jpg page 51 Keith
