I'm having a blast with my new 2015 KIA Soul. With the purchase I also have a 3-month trial subscription to Sirius XM radio. I've pretty much figured out everything as to how to use it and select what I want to listen to. (Thankful that I CAN actually LISTEN to the radio again!) But, I can't seem to find any controls over Treble/Bass and Speaker controls. The MENU option on my radio only shows an option for INFO. Should there be any Treble/Bass and other such controls?
