I have both the d3 and the kenwood ddx 7019 (same as the dnx 7100 without the nav built in) with the nav ad on. I must say, the sound quality on the d3 is better in my opinion. Not to say that it's bad on the kenwood because it far from bad, just a little better on the pioneer. The video quality is just as good. It took me a while to get used to the Kenwood (gotta read that manual) but after that I found it just as easy to use as the d3. As far as nav goes I like the detailed maps of the d3 better. All in all, I would recommend anyone still on the fence between the two go to a local shop
