Nick, I was just looking at their special 2 days ago, and I will most likely call them tomorrow for details.
dj, I got it at a fantastic price, about $300.00 off suggested retail. I got it just as it hit the market and I believe the 5700 was being replaced. It would be great if I could remember the website that I purchased it from
I didn't have to use any additional parts since the parts were already in place from the Sony head unit.
