I installed my own SPORTSTER (Sirius).. Although a bit simpler.. I just placed the antenna near the windsheild on the right side of the dash. I tucked the cable down behind the dash and under the door moulding, down the door moulding to under the dash, accross under the glove box and through the little opening on the side of the center console box with the pop up lid. I made a small block of oak and mounted the base on it which slides right into the opening and holds the unit securely. Works just great and I can close the console cover most of the time unless switching channels.. Be nice If I had a remote for it but for $49 bucks, I can live with it.
I wouldn't think it would be worth it to have the on-screen stuff, since it is like $500.
