Anyone installed a LCD screen and or a dvd/tape player in their Element? If so, what are the specs, do you have pictures of your install, did you do it yourseld and if so was it hard? I've been looking through a Crutchfield catalog and saw a LCD screen that mounts on the driver or passenger headrest for $199. Then there is a small dvd player built for a car for $179. What have ya'll found or used?
