My GTS has the Bose sound system. The manual refers to a Loudness function setting, but there is no option in the menu...just usual bass, treble, etc.
Am I missing something?
The linear function is good...

Check out options under the Sound button. I think it would be there if anywhere.

Setting the Loudness* (from the Porsche on line manual)...

The Loudness setting increases the sound capacity by accentuating the low frequencies (bass). This has the most noticeable effect at lower volume levels.

Surround (Bose® Sound System)

The Centerpoint® signal processing system generates multi-channel surround sound from standard stereo sources such as CDs, radio and MP3s. To achieve this, the stereo signal is continuously analyzed and converted into multi-channel surround sound using Bose's patented algorithm. SurroundStage® signal processing, a Bose technology, sends the surround sound signals generated in this way to the appropriate speaker, thus offering the listener a well-balanced 360° listening experience

Press the SOUND button.
Select "Surround".
Surround is switched ON or OFF .
*) not with BOSE® Sound System and Burmester Audio System
