tonydgs400 Posted March 15, 2008 Share Posted March 15, 2008 my navigation screen blanks out & comes right back on, no matter what i have it on. eg: radio, cd, tape. "BUT" when the car is in park the unit works fine....as soon as i start to drive the whole unit shuts down & what ever i am playing shuts down also eg: radio, cd, tape and comes right back on.......i disconnected the battery & its still doing the same thing, when i first turn the car on i cant touch the screen to operate anything i have to press the manual button. & the screen keeps saying low fuel although my tank is almost full & if i turn the unit off the screen starts back up, the navigation does not come on at all anymore even if i touch the manual button, a few months ago when i tried to press agree on the screen it would say DISK COLD......could someone help me please thanks in advance for your help Quote Link to comment Share on other sites More sharing options...

I think, during engine start the battery drops and the power supply would be a diode plus cap thus the drop is isolated, if the cap/diode dead the low supply passes through and causes problem.
