Hi there i have an 04 530i the 6disc cd changer, bluetooth, voice commands stoped working. went to the dealer to get an system update see if this would fix it and they could not do it. they told me to change the cdc unit or ulf one of them has a problem. and come back to get it done, could you guys give me some advise on the problem i dont wont to go spend money for stuff that isnt needed. everyhing stoped working at once. thanks

 

and also the cd player from the dash is now very lagy it starts 5 10 min after i place the cd in i tried over 20 cds and its the same after a couple of tries it starts working.

 

Same as my issue, did you manage to get it sorted?

 

Anyone else have this sort of problem? My 05 loads the CDs (you can hear them loading) but won't allow me to play any of them. The single CD player works fine, but not the changer. Also have an issue with saving presets on the FM and AM.
Anyone have some advice on these issues?
