Install Sirius and iPod hookup help

I have a 05 Prius with 6 dick changer and want to integrate the Sirius and iPod into it. I was told to use I simple so I purchased one and hooked it up but never got the screens right and never could get it to work right with sat and iPod while connected to the isimplesolutions box. I have researched and I believe I was misinformed on the I simple working bc it seems I may need a radio with sat button as well. Funny thing mine don't have sat button but I could press am twice and it would go to a sat screen but no info or sounds coming in. I'm baffled with it now. I just don't want a sat standalone unit on the dash but looks as I may. Does anybody have sat and iPod in a prius without the sat button the radio? Thanks for the help I appreciate it.
