SIRIUS Radio in an 07 H3

Has anyone sucessfully had their '07 stereo fitted with the in-dash after market SIRIUS radio receiver from Crutchfield or Soundgate? I am unable to get an difinitive answer as to if these are compatable with the '07's as it seems as if there has been an equipment upgrade in the newer models that may affect instalation (which is different than the '06)

(note: I'm not looking to add a portable unit as in all of my other vehicles but rather use the "mode" button on the factory stereo touch screen much like one would for XM)

Edited to say I should have read that you are using it for an 07. I use it on my 06, works great.

I was told that if you have the 6 disk changer it won't work.  I'd love to hear if anyone has tried it though and what the results were.  It still seems strange that it worked in the o6's but not the 07's, why screw up a good thing.
