Installed my new XM radio today, love it!  Found it onsale at Circuit City for 255, with free activation, and a 25 gift card too!   Hook up was easy, I mounted the antenna to the front of the westy roof rack with double sided tape, the angle was a little radical, but reception is superb. 

PS-  How can I check my fan relay, seems to only come on at one speed?  Is it supposed to turn on automatically with my AC, cause it dont?....
