This is a wired remote controller for my Sony head unit installed in one of Silvia’s 2-DIN slots. I specifically bought this toy because it had been around for at least 10 years and I thought it would be dropped in favor of a new model. Bingo! I was right and the new ones are wireless, though less 80’s-looking and hence worthless in my opinion. I think I may be one of three people in the universe who can change the settings for the subwoofer output’s high pass filter one-handed in the dark without looking at the display. Now somebody give me A GODDAMN COOKIE.
