After removing the frankly hideous aftermarket Sirius antenna on my car - I looked in the stereo slot to fish it out the antenna wire and saw it plugged into a Sirius thingy - unplugged for now - which was plugged into another box with miles of thick blue wire. Anyone know what the far box is? I’m going to leave it unplugged for now - but ugh. Sirius radio? What is this 2012? Why so Sirius?
