Actually the picture is not my bike, nor do I have the XM module on my bike yet. I do however have Sirius/XM in both my Jeep Cherokee and my wife's VW Jetta.
My antenna is placed on top of the roof of my Cherokee and works quite well. I still lose signal around very tall buildings, when driving through forested areas, and anytime I go under an overpass. Overall it's a pretty reliable signal.
I installed an upgraded VW head unit in my wife's Jetta which was not originally equipped with sattelite radio, thus it has no factory roof top antenna. I mounted her antenna on a piece of steel dash support, just above the head unit. The signal must travel through her glass windshield, her plastic dash, and some A/C venting. Her signal is nearly as reliable as mine, except on overcast/cloudy days when it tends to drop out occasionally.
Moral of the story, a clear view of the sky is going to give you the best signal. That being said... if the signal can make it through the multiple layers of glass and dash in my wife's car, I'm pretty confident the plastic fairing on the XC shouldn't be that big of an issue. When the day comes that I get XM on my XC, I plan on leaving it in the factory location.
