Need some suggestions for Navigation

[Team AI]

Well it's been a while since my last post, been crazy busy but I'm back and I need some help. I recently retired my Mountaineer and replaced it with a 05 Kia Sorento LX. I need to put Navigation in it before thanksgiving. I need a double din HU and so far I have looked at a couple of Eclipse HU's but they don't have a surround processor witch I would like for future additions. I was also looking at the new pioneer and a kenwood in dash DD DVD w/ screen and a stand alone nav unit. I kind of like the kenwood because it doesn't require a DVD for navigation and can be upgraded and I can get the two parts for around 1100. I am open to suggestion though so let them fly.
