COLORADO-LX470man

I have an 2002 LX470 with the factory NAV unit installed and want to add satelite radio to it. I know I can do an FM modulator side by side unit but I wanted something a little more built in and controlled and displayed on the NAV screen. Does anyone have any ideas that can make this happen?? Thanks in advance for any help... Mike
