Volume and sound settings
You will find details on volume and sound settings in the "At a glance" section.
WARNING
External video sources may have different
volumes, which can mean that system
messages such as traffic announcements and
navigation system announcements are much
louder. If necessary, please deactivate the
system messages or adjust their volume
manually.
In some cases, the volume of the AUX
device may be quieter or louder, or the
usual maximum possible volume cannot be
reached. On some devices, it is possible to
adjust the volume separately. In this case,
start at a medium volume and increase it
gradually. This enables you to determine
whether the system is able to play the
music at high volume without distorting it.
