My car's software has been updated to the latest iDrive yesterday.
They forget to enable the MP3 Retrofit option however (yeah, i know, smart move... I asked them specificly to enable it...).

I've connected the Dension 500 to the fibre optic ring and to the powersupply.
The blue led is constantly on, confirming the fiber optic ring is okay.
However, i can't select any of the CD changer CD's (they are grayed out), i think this is because of the MP3 Retrofit option not being enabled, but i can't be sure.
Does anybody have any experience with the Dension 500?

Next question:
I updated the iDrive software in the first place, because my iPhone couldn't detect the car's bluetooth.
The bluetooth works, as my Nokia N73 does detect and connect to the CCC. (BMW##### is the car's name, where the #'s are numbers)
After the update, i still couldn't detect the iPhone. I've tried several iPhone's (All 3G's with the 2.2 firmware), but none of them detect the car.
Does anybody know what's going on?
