Time for an Integrated XM Tuner...
				
				While I was installing the 
				Pioneer 
				CD-IB100II iPod 
				Adapter, the XM radio caught my attention too.  Why was I 
				going to leave the Roady XT XM radio hanging off the dash when I had done 
				such a good job getting the iPod completely integrated?  
				There was no good reason.  I found the part number for the Pioneer GEX-P920XM XM tuner component and ordered it.
				
				
				
				
				The beauty of the IP-BUS 
				connectors on the Pioneer is that you can daisy chain from one 
				external devices to the next using the single IP-BUS input on 
				the back of the head unit.  Each component requires its own 
				power and ground but with the auxiliary fuse panel I installed, 
				that was also very easy - just plug the yellow into the "always 
				on" side and add the ground wire to the ground post, run the 
				satellite antenna and Poof!  
				Done.
				
				In the process I removed the 
				Harman/Kardon Drive + Play items.  I will install them in 
				the Jeep since the Pioneer head unit there does not support the iPod Adapter and I had found that using the iPod with a cable 
				and separate power cord was cumbersome.  So I can reuse the 
				Drive + Play and have only one redundant XM Radio (that cost me 
				$9 in an online promotion).  With the 
				Drive + Play and XM 
				radios removed, the wiring scheme is greatly simplified. 
				
				I left 
				the AUX mini jack available outside the dash for guests or 
				future indeterminate devices.  It took me longer to update 
				the wiring charts (below) than to do the actual work.  But 
				given the slight complexity, it will be handy later when my 
				memory fades, what's going on with all this stuff!
