Sorry JayZ, no pics. I didn't really think about it, since it's such a simple install.
Tierra, sorry to say it, but with the factory Satellite radio, you can't use the AAI-NIS. It uses the same jack in the headunit as the factory SAT receiver, so you can't have both.
As for the FM modulator, it taps into the wire that runs between your FM antenna and your HU. You set the modulator to a certain unused FM station, so when you set the FM radio to that station, the modulator cuts the signal from the antenna and "broadcasts" its own information. It works fairly well, but the sound quality is only about as good as your average FM radio station. Plus there is some residual static from time to time.
