Just like to ask the people who have got the RT-S already if the Sirius Satellite Radio came with it or is it a upgrade the site don't tell you. I know the CB is a upgrade but there is not much that is not on it already.
It does not come with it. You have to order from your accessories department. I ordered mine about three weeks ago. They said it would be sometime in February before I would get it. Same thing with the ZUMO 660 GPS. Hope this helps.
