Adding Sirius to 2012 Prius TWO

I am trying to add Sirius to my 2012 Prius TWO. So far I have purchased this:
SiriusXM Connect Satellite Radio Vehicle Tuner Black SXV200V1 - Best Buy

What else do I need? Or is that I will need for a "plug n' play" installation?

 

Cant I just use the SIR-TOYSC & SCC1 that I had installed into my 2007?

 

Ok so I tried to install the SIR-TOYSC1 and SCC1 from my 2007 and it didnt work. Although the plug fits in the back of the radio, it doesnt seem to want to go in all the way (different pin-out?) I didnt force it....but it does seem like the same plug.

Do I need to do anything to have the head unit recognize the Sirius install??

 

Welp, no workie then. I just ordered the I-Simple ISTY12 which says it works with my SCC1, so thats cool. Just in case, I went and bought a new tuner from Best Buy (Svx200 or something like that). I just want my Sirius working so I can move on to my backup camera install next & install an auto-dim HomeLink Mirror!
