I know you have the 05. But. The 04-03 have a dot to the upper right of the far left digit if in the kilometer mode. If it is in kilo and you want to switch to mph. While holding down the speedo button on the face of the speedo, turn on the ignition key and the speedo display window will show - - - . At this point keep holding down the speedo button and after approx. 7 sec. the display will go the odometer reading with the setting changed. The dot will have disappeared if in mph. Good luck!
