Speed Dependent Volume Control
Description
If activated, the radio output volume will be automatically adjusted to compensate for increasing driving
noises at higher driving speeds.
The radio receives a speed signal from the vehicle speed sensor (VSS) and selects the output volume.
Personal Audio Settings
Description
The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed
dependent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be
registered. During the communication as mentioned under“Anti-theft System”, the radio will recognize the
used ignition key and select the accompanying settings.
