JAT on this, as I'm feverishly finishing the acquisition of parts to install a mygig into my '06...I currently have the non-nav dumb 6cd setup in my XK, but I bought a little isimple box that allows me to hook up my iphone through the unit and stream SiriusXM. I have an old unlimited plan, so I don't worry about data usage. Point being, if you find something that can connect and control a smartphone, you could add a streaming account to your Sirius sub and ditch a radio sub at the same time. For the last 5 years or so, I've only carried a streaming plan.
