Hi, Namcars.
Put your key in the ignition and turn it two clicks (the engine can be off). Make sure the car is stationary, and then press the menu button (on the steering wheel) repeatedly until Settings appears (in Japanese, it is: 設定). Next, use the down button to select the 5th line (which should be Language - 言語), and select English. Press OK, and you're done.
Hope this helps!
