Question about 2004 Audi A8
I should have this system in the car but I get a message saying " Check navigation cd"
The player would not accept the cd and the agency told me that I need to change the control unit.
And I also want to operate the handbook but get the same message. Is there anything I can do other than changing the control unit
NAV unit uses a DVD disc. If its a copy, it may or may not work. I suggest you remove the NAV disc, unplug the NAV unit from power for 4-5 minutes, reconnect the NAV and try inserting the disc again to see if it reads. If it still does not read, another NAV disc needs to be inserted to verify its not a "bad" NAV DVD disc issue. If it still cannot read the second disc, the NAV unit is bad. The handbook feature needs the disc inserted in the slot 1 of the CD changer unit.
