This unit plugs into the back of the MFD and allows for Sirius radio to be integrated directly with your audio system. It is described here on the Factory Interactive website. Factory Interactive - SIRIUS Satellite Radio for the 2004, 2005, 2006, 2007 and 2008 Toyota Prius The only difference is that the antenna I have is older than the antenna pictured. It works perfectly, I just no longer have a Sirius subscription and I do not plan on getting another one. Original price was $395.
How old is the kit? Do you have the base or JBL stereo? And do you still have the instructions or DVD? Thx.
