This was installed in my SC for about a year and was removed when I sold it. Link to Alpine site with specs/features/owner's manual/etc here: http://www.alpine-usa.com/US-en/prod...model=CHA-S634
I bought this for around $350; it's yours for $150 + shipping. It is in perfect operating condition when removed from my car. All you will need is an Ai-net cable to attach this to your Alpine head unit (obviously only works with Alpine stuff).

Thanks for looking.
