I'm next week gonna order a W211 (T-Model) with either Audio 20 or COMAND APS. Really i'm most interested in a really good sound. As I already have a separate navigation system, Navman iCN630, I shouldn't be needing the NAV.
However, if it appears that the sound is MUCH better with the COMAND i'll go for that anyway.

Now to my question.
Are there the same number of speakers used for Audio 20 and COMAND APS ?
Have anyone listened and compared the hi-fi difference between thoose systems ?

Is it possible to remove the DVD player protection while driving ?

Thanks in advance!
