Here are few pics which show the procedure to change / adjust the time / clock of Honda Accord CL9 Japanese Verison:
Hey guys, just a quick tutorial for those owners with the imported Accord CL9′s from Japan that came with the Navi/GPS screen.First, press and hold the buttons circled in red at the same time for about 5 seconds.
Then a hidden menu will appear, this menu has a lot of buttons but unfortunately it?s written in Japanese. If anyone can translate it would be very much appreciated. Now, press the button circled in red.
Same procedure, press the button circled in red. This will bring up the GPS time.
Now you can adjust the day and time! Oh, and don?t forget to press the Enter key to make the changes.
Now press the yellow button to exit the menu. Enjoy:
