For the first time yesterday when I hit the power button to start the navigator all I saw was some sort of distorted image that flashes on and off rapidly. I do not get to the 6 panel touch screen, this problem happens immediately after I hit the power button. I shut the system off several times and waited as it flashed for some time to see if it reset but nothing. I shut the "electronics" button on the dashboard off and on no luck either. Thanks for your help in advance. 2005 390 DA.
