The audio CD or navigation DVD cannot be ejected from the RNS-E optical disc slot behind the navigation screen. The adaptation for enabling the eject button was either not performed at PDI or was not performed correctly (with a bus sleep immediately following the adaptation change). If ODIS OBD self-diagnosis was used, then it's possible a value of "1" was used, or if using the GFF test plan, the "CD/DVD Ejecting" option was incorrectly chosen. Setting the adaption to "1" or choosing the "CD/DVD Ejecting" option, is a one-time eject option that allows the ODIS tester to only eject the CD/DVD. This option does not permanently change the adaptation value and as a result the eject button remains disabled.
