I tried to find what I needed on a search but I am still confused. I have the SE with the rockford fosgate system. As I understand, that system is compatible with sat. radio. What do I need to buy to have it work. Is thare still a separate tuner needed or does it just work through the in dash tuner? IIf I am underatanding this right, I have a plug that the sat. tuner plugs into, Right? Can someone make it simple for me to understand. Thanks

Yes, you have to get a box that plugs into the current truck stereo and the antenna that goes with it. Your local dealer can probably order it and install it(if you don't want to). Or you can order it online and install it yourself.

Thanks guys. Wow army theres a big difference in price for the one you posted a link to. And I noticed that it comes with everything including a three month sub. Thanks for clarifying all of this for me.
