I have used this HU for about 6 monthes and it is in perfect working condition. It has 2.2v preouts(2 of them), sub woofer drive control, and is XM ready. Great HU, I just got a really good deal on a high-end Alpine HU that I couldn't pass up, otherwise I would still be using this. I will sell it for $105 shipped. There is one very small scratch on the front on one of the buttons. Otherwise it is in perfect condition, and it comes with everything it came with: remote, wiring harness, manual, trim peice, mounting frame and even the original retail box. E-mail for pics. Hop on this deal quick!
