Just added an 05-06 Nav to my 03 H2 now about XM...

Sorry, realized I forgot to describe how hard the mod was! There are some awesome instructions in the forums on how to install the NAV, I just printed them out and followed along, not hard at all if you've ever installed a car stereo beforeand have the right tools - socket set, screwdrivers and Allen wrenches. At this point I can take the center console out and pull the radio in the dark, I've done it so many times. The NAV was PnP and the XM Direct had a harness adapter that was pretty much PnP as well.

Have fun!

I live near the Edelbrock dist center so I did will-call and paid a muffler shop $90 to install it. I think Edelbrock is getting rid of some excess Cat Back stock because this is the same system that sold for $400 or so last year, you are buying it directly from the manufacturer so it's pretty much worry-free!
Had it on for a month now and no problems, sounds great!
