I managed to access Dealer - Test mode on my K5 Optima hybrid as I show in this video (Settings button pressed for a few seconds, then keeping my finger on the middle of the screen for about 10 seconds, then entering the password: 123456.) - unfortunately couldn't find yet how to access Windows CE 6.0 desktop interface
