Premium sound help.
I have searched the forum high and low, read the owners manual and now I need some help. We have the premium sound package in our "is". I cannot find the menu option to set the surround sound feature. I believe it has "cinema, concert, etc". I have founf "gong" and set the EQ but unable to locate the surround feature. Can someone help guide this inept owner to the proper menu? Car does not have Nav so no i-Drive.
