Automatic volume and tone setting

WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

Using continuous microphone measurement, the High End audio amplifier identifies annoying tire or wind noise. The High End audio amplifier dynamically adjusts the volume and the sound quality accordingly. The "Speed Volume" setting is thereby replaced.

NOTE: Surround sound functions are not recommended under certain circumstances!

The surround sound function is not recommended for predominantly voice reproduction or poor radio reception.
