I've got a Boxster S 986 (2003) with a cdr 23 + Amp as sound system (option M490).
I was this morning by my dealer to perform a clima service. I asked the engineer if he can program the option "adaptive sound", so that the volume increases with the speed.
He replied me that he couldn't program this option? he couldn't find it on his computer, the famous PIWIS.
Does anyone know something about this feature ? Is it possible to program it direct on the CDR 23?
Thank you in advance !
