Just got a nice new 2010 Santa Fe Limited with Nav and after trying to learn all the features I'm really enjoying it. The only thing I can't figure out so far is how to mute the radio but that's a minor thing. I'm looking to a number of good years of driving.

 

The info is in the Navigation System manual. Pages 8 thru 11:

 

Thanks for the info but mine doesn't have a steering wheel mounted mute and it's a pain to go into the nav system setup menu to mute so I'll have to figure something else out.

 

The manual says the "AUDIO OFF" button will also mute the system.
