See my response from another thread (below). With the USA-SPEC ipod adapter, you can use the RCA input for an MP3 Player, as well as use the ipod interface. I ran the wires from the XM receiver (back passenger side, behind the subwoofer), to under the carpet in front of the middle seat, then under the carpet at the "hump" and up through the carpet into the center console between the front seats. I placed the USA-SPEC box (it's about 4"x3"x2"), in the center console compartment behind the cigarette lighter/power socket. The ipod and RCA input wires come up into the mesh pocket in the back of the console. You need to have factory XM for full functionality, but it also works without XM.

From another thread...
I am adding both an ipod adapter and auxilary input (audio only) to my SRX. The unit is a USASPEC Pa11-VETTE iPod and RCA interface. It works on new Vettes and SRX with XM Radio. I'm not sure what year's SRX are covered, but I know it works with 2005.
It plugs in between the XM and the Radio, and allows:
- Ipod control using the XM-1 on the Radio/Nav (P1-P5 are for playlists, and P6 is for normal iPod Play). You can use the touch screen and steering wheel controls to control the ipod. Shuffle, random play, and other iPod functions are controlled through the touch screen.
- It also charges the ipod, when connected, and automatically stops charging after 1 hour.
- It includes a seperate RCA interface (which uses CD6 - Track 1?) for connecting another device, like back seat Video, mp3 player, etc. I will probably use this to hook an aftermarket backseat DVD system to the factory radio.
I'm still trying to figure how I'm going to run the wires and where I'll mount the I-Pod and RCA cables (probably in the center console), but I should have it in over the next few weeks. I'll let everyone know how it goes, plus try to take pictures fo the install.
