  1. Ignition OFF, allow the navigation display to cool if the ambient temperature inside the vehicle is excessive and the radio is hot to the touch. Verify the navigation display is cool and the DTC has cleared and gone to history.
  2. Ignition ON, with a scan tool, clear all DTCs and operate the audio/navigation system within the Conditions for Running the DTC.
    • If the DTC resets, replace the radio.
