The Roady is very compact and comes with a little swivel stand that goes between the ashtray and shift lever (self adhesive). When you take it off to go inside, the little do-hickey doesn't look that bad, since it's black and matches and all... I'll try to take a pix and uplink when I get some time. I routed the wire to the Alpine (new receiver I put in that has an "AUX" input) through the ashtray, so I can store it away when the Roady's in the house. My subminiature XM antenna is double-side-taped to the right side of the dash and wire is routed along door opening under glove box and up to center console, so it too can be tucked away. Power is from lighter jack. Works very well and sounds fantastic.
Best thing is the 10.00/month for one receiver is serving both Viper and office. (I do have another receiver in the daily driver that is not removable, but they discount the second receiver, so all in all, not too bad.)
Once you go XM, it's hard to listen to anything else.
