Sat disconnect location

[CcDubya]

Can anyone tell me the best place to disconnect the Satellite. I'm having the iPod kit installed at some point this week, and the boneheads at my local dealership don't seem so sure of themselves. I'm thinking I might just have them put it in, then I'll take care of the sat disconnect myself. I'm hoping it will allow me to always be directly on the iPod.

Someone had said it was located in the trunk somewhere. Anyone have more specific instructions?
