Ever since I purchased my 2005 sc430 my navigation system powers on when I start the car but within a few seconds it says Bluetooth failed and then the screen turns black everytime. After reading up on the navigation system I realized that there's supposed to be a cd in the navigation system in the truck so I located it I can hear the motor on but there doesn't appear to have a cd in there. Is this why the screen turns black after a few seconds of powering up the car? Would buying the navigation cd fix the problem

 

Accidental repeat.

Press eject button to confirm if there is or is not a cd in the unit, if not, get the nav cd on ebay and your question will be answered
