My car has no built-in dvd player. This in-dash dvd player works great for me. I can use it for navigation and also hands-free calling after syncing with my iphone via Siri. It loses point just because of the high price.
I can't say that technology produced by this company is state-of-the-art. But I can definitely say that they provide the most reliable electronics I have ever used.
All of electronics that I have purchased are in working order even after years of use.
I think that many people like me choose Kenwood for this reason.
