I have the Kenwood KVT-514 in my Ram and love it. I've had it for a few years no without any problems. I know that now there are ones that offer what this one has, but at the time this was one of the more reasonably priced ones that showed the cover art off of the iPod and was something I really wanted. I have an old iPod in my glove box that I never touch and can work everything from the head unit. I know it is an older model so you should be able to pick one up for a pretty reasonable price. Like I said, mine is a few years old and I have it where my screen automatically opens and closes everytime the car is turned on or off, so it has opened probably thousands of time and never failed. I would recommend it.
