#PIC4858A: Navigation Radio CD Error - CD Player Will Not Accept Discs - (Feb 11, 2013)

This PI was superseded to update the photos. Please discard PIC4858.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern

Some customers may comment that the CD changer (CDX) will not accept CD’s or the display shows a "CD Error" message when attempting to play a disc. This will usually occur after the radio or CD changer was recently serviced for a different customer’s concern.  This may be caused because the ″shipping pin″ was not removed from the bottom of the CD changer prior to installing the service part into the vehicle.

Recommendation/Instructions

Remove the shipping pin from the bottom of the CD changer prior to installing into the vehicle. This item is called out by an arrow in the first picture below.  The second picture shows the shipping plug that has already been removed from the CD changer.

If returning the Navigation radio to the Electronic Service Center, be sure to reinstall the shipping pin to prevent damage to the unit while in transit.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
