navigation headunit problems

[em2b96p]

i get CDERROR 9/10 times i try and play a CD-R and i cannot play MP3 CD-R's.

also i get CDERRORS when playing regular cd's sometimes and ive already tried cleaning the lens with one of thoes cds with little brushes on them.

anyone else experiencing the same problem?

No - how old is your car?

MP3 was only available late 2004 onwards.

i have a 2004 3.0i with the standard navigation head unit. my car was made 8/04. will not play mp3 cds and gets cderror messages alll the time.

If the head unit is black it will play MP3's, of it's grey it won't.

I found out something interesting today.

when i have a passenger the airbag off light dissapears. then the headunit would play CD-R discs. then when the passenger gets out and i try and play the CD-R again it will not work.

due to resarch ive concluded that the previous owner of my Z had an AUX installed and now removed and possibly a cd changer as well. when they removed the aux and cd changer is there deprogramming that needs to be done?

No reprogramming required on the headunits, the bus automatically detect the unit - hence the no need to enter any activation codes.

CD changer and AUX are all independent settings on the unit, so if they have been removed it automatically detect it is no longer there.

The AUX and CD player are a plug (white) which can be inserted / removed from the quadblock without problems.
