I'll second Heraclid's asessment of signal clarity. I drive regulary in downtown Tampa and Orlando plus my local downtown areas and rarely have any issues. The antenna on the Dragon is mounted on the hood insert and the antenna on the Iron Man is on the rear portion of the roof. Both pull in quite well, unless I'm stuck in traffic under a building-to-building bridge or similar. In metro Atlanta I've had no problems either, but you've got to realize that both SIRIUS and XM have ground-based digital repeaters for areas that may have a lot of "sky clutter". These two companies didn't just throw this service on to the market without developing infrastructures to support them. That's why there's more channels than the original 100: Technology has improved in the few short years since satellite radios advent which allows for greater compression, thus more channels for such things as regional/metro weather and traffic. In the case of SIRIUS they'll be offering video as well for in-car systems.

Now for mounting options, there's plenty. My original system in the Dragon is the Kenwood FM modulating unit that can control both a SIRIUS tuner and the MusicKeg digital changer. I cut out the cover for the ECU and mounted it there just below the CD changer. Works fine but the non-adjustable display is a tad bright.

The Audiovox portable tuner I got for the Iron Man was originally mounted (via its docking cradle) in the fuzzy hole with a simple aluminum bracket I fabbed. Well, at night the display reflected directly in line with the driver-side mirror so re-location was in order. I ended up mounting the docking cradle to the ECU cover again, offset to the left. It sits just below the CD changer and ahead of the gear selector. Perfect position! I can see the display clearly, reach all the buttons and my leg doesn't rest against it. As soon as another ECU cover arrives from St. Charles I'm installing another cradle in the Dragon so I can retire the Kenwood unit. I love the portability of the Audiovox! I wish I had waited a bit though as Clarion has a new smaller SIRIUS portable that's the same size as the Delphi Roady. Who knows, those things are so cheap I may switch the next sale at Best Buy! You can always unload the old ones on eBay too!
