I just put my head unit it. I looked at the Pioneer, as well as a few others, like the Kenwood DNX7100, but opted for the Alpine IVA-W205. I liked the Pioneer unit, especially the HDD, but I've always been an Alpine fan.
I've had mine in for a few months only complaint was the first day i got it volume was real low took it back the next day and bestbuy fixed it. Sounds great even with stock speakers, love using my i pod with it, touchscreen is cool and the navigation is really good. I'd say it was money well spent
