I installed the Sirius adapter today and it works great. The volume is about 1/3 louder than the small wire antenna that the receiver came with. It just plugs into the back of the Sirius receiver cradle so you can unplug the unit and move it to another vehicle just as easy as ever just plug in the small antenna wire that came with the unit. The wire that plugs into the receiver and runs to the antenna switch box is 18+ feet long and the antenna wire that plugs into the back of the radio is about a foot long. I like it Total with shipping was 25 bucks.
