Anyone have their XM Roady installed in their vehicles? I'm looking for mounting ideas for the unit and placement ideas for the antenna. By the way, a huge thanks to Cards81fan for the post letting us know about the Dockers/XM Radio offer. I got some pants that I needed anyhow and a free XM radio and 3 months paid subscription -- they're trying to get us hooked I'd prefer something non-permanent so I can move the unit from the wife's truck to mine, but that's not necessarily a hard requirement. I could get a 2nd antenna if that works out to be easier in the long run...how much do those antennas cost?
