After a radio is returned from the Electronic Service Center, some owners may comment of no radio navigation operation and a CD ERROR message displayed on the radio
Bulletin 07-08-44-014 provides a service procedure to resolve these conditions.
Check a navigation radio that is returned from the Electronic Service Center before customer delivery.
When following bulletin 07-08-44-014, the radio will display an Update in Progress screen (fig. 10) which indicates that a successful update is being loaded into the radio. After the update is complete, the radio should operate as intended.
