Thanks to Squareback who put together this tutorial.
Thanks to the following people, for providing their experiences and information, without them and the .net, I would be using the lowly tape adapter for my Ipod and the FM Transmitter for my XM.

I read all the FAQs (mainly this one - http://my.is/forums/showthread.php?t=220767&highlight=aux+relay), and originally decided to go the PIE route, but had second thoughts and went the relay route, as I felt it fit my situation better. (Mainly I'm cheap, and I didn't like the idea of jerry-rigging the PIE switcher to fit our needs for the Aux-In)
The following parts used were:
1) 4PDT Relay
2) 14-Pin Relay Socket
**I used the relay screw socket to make it easier than working on those little pins and in case a relay blows, I can just pop in a new one.**
3) 2 female RCA jacks from Radio Shack
4) Pro-Fit VSM Mount
5) 3.5MM to RCA jack cable
6) SPST Switch (to control power to the relay)
7) Power Socket from Radio Shack (to hard-wire the power)
1) Pop lint tray out with screwdriver
2) Unscrew dash tray - 2 Philips head screws
3) Pull dash tray out and up to remove from dash
4) Pull out switch tray from below radio
5) Tape up sides of dash to prevent nicks from radio as you remove it
6) Unscrew two 10mm bolts from the top or radio and below radio
7) Unplug AC harnesses, radio harness, and antennas from behind radio and remove
8) Pop console up with a screwdriver behind the chrome trim and remove, need to unhook cigarette harness, ashtray light, cigarette ring light
1) Ignore AC harness and grab radio harness
2) Cut back the black casing and look for shielded white casing with green stripe
3) Separate and cut white, red, green, black (Brown if you have a 2001)
**Make sure where you cut the wires that you leave space for the relay socket to fit behind the radio and harness connector when you reinstall the radio. I almost made my HU side of the wires too short and the relay was bumping up against the back of the radio when I reconnected the harness**
4) Attach W,R,G,B to 1-4 on relay socket, this is your HU signal
5) Attach W,R,G,B to 9-12 on relay socket, this is your output to the amp
6) Attach 2 RCA females to 5-8, this is your Aux Input
**Order of wires doesn't matter as long as they correspond (L+, L-, R+, R-)**
7) Pin 13 and 14 are for ground and power (either one works for either)
8) I attached 13 to the switch ( I will later hook-up the switch to the pink (positive) wire on the cigarette lighter, but I did it in conjunction with the power hard-wire, so I will get to it later)
9) I attached 14 to ground using one of the "bronze" screws under the console, directly below where the ashtray would be
10) Push in relay into socket
Hard-wire Power Install:
1) Used the "bronze" ground screw directly under where the ashtray would be for the ground on the power socket
2) I soldered the positive lead of the accessory socket to the positive connector (pink wire) of the cigarette lighter.
I had to remove the plastic clear case around the connector, but after soldering the accessory power socket wire and the power wire for the relay via the switch, I slide the plastic case back on the connector for a nice snug professional fit. I also did it this way, because I didn't have to cut the stock positive cigarette lighter wire.
I plugged in the power cord from the RoadyXT and tucked it up in the dash.
1) connect one 3.5mm to RCA Jack to the female RCA Aux-In jacks
2) Route Power and 3.5MM wire out dash tray area
3) Line up Pro-Fit Mount with top right radio screw hole
4) Reinstall radio, dash tray, lint cover, console cover, and switch holder
5) Mount XM to Pro-Fit Mount, and hook up power, line out, and antenna
6) Flip the Aux-In switch and enjoy!
