I have the AVN 8435, it kicks ***. I got it for only $1150 at The Good Guys because they are going out of business. If you're in the market for it, I'd recommend checking out your local Good Guys to find one for cheap. You might have to go to a couple different locations to find one in stock. In my opinion, the has much better Sound quality than any of the other available double din nav units. Ultimately that's what will matter after you are done playing with the features.
