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!
