Very brief question, done a bunch of searching and can't come up with the answer I am looking for. I have an 05' X5 4.8is with a Mk.4 navigation unit.

I like to have guidance to a destination for distance and time of arrival information but don't want to hear the voice giving directions. Is there a way to completely mute the navigation volume while it is giving route guidance?

Nav volume under settings is turned down completely and under the info menu I have Nav Min set to -9.

Thanks for any help in advance.
