The direct connection through the CD changer port has the best sound quality but the adapter costs a little more (not much more, considering the cost of the antenna cable adapters). Or, if you have a cassette head unit, you can get a cassette adapter for around $10.

Here is my install:

I originally had a wired FM setup. Although better than wireless, it still sucked. I often had to switch which station it used because strong local stations would spill over onto it. I now have a GM9-AUX adapter which converts the CD-Changer port to RCA AUX-IN. That adapter will work with 1998-2002 Cassette headunits, 2000-20002 CD headunits, and some late 1999 headunits (the ones that were able to control the CD-Changer).

Either way, I'd recommend a wired AUX-In approach instead of a wired or wireless FM approach.

BTW, do you know that you labeled the spare wheel the spare tire? haha

Seriously, I was doing some last minute research before I install my satellite radio.
