I had the Kenwood DDX7015 with the DV3100 navi in my old Maxima. It performed very well, and I had zero complaints. When I sold the car to buy my 05, I sold the stereo/navi as well.

Now, I'm looking at an Eclipse AVN5435 or a Pioneer AVIC-D1. I'm well aware of the differences. I prefer the Eclipse, but cost may lead me towards the Pioneer. I never watched movies in the car before, so that's not much of a problem.

The reason why I'm not going towards the newer Kenwoods is because I want an all-in-one self contained unit. I don't want to have to figure out where to mount the navi unit. With both the Eclipse and Pioneer, the navi is built in.
