xm radio tunner
No, but the guys at the stereo shop near my house said it would, and from my experience with car audio, I can not see any reason why not, however, I have the navigation model, which is just a rebadged Kenwood unit, you might check with Suzuki and see if the XM tuner for both the regular and navigation models is the same part number.
