Dose the upgrade radio change out the speakers as well. It seems like that on their site. I don't understand what you get is it just a head unit alone?
Also, I have a pioneer head unit with the XM radio hook up on my tC. I know that the stock radio needs a different connection to plug into the stock head unit. Now will the upgrade radio have a basic pioneer XM port like the aftermarket pioneer radios or would I still need to buy a Scion plug.
