Good buy - the delivery was made on schedule and the package well conditioned. The main screen was not working. A new set I was sent very quickly and without any problems following my call. The new main screen works and I return the first through the return label received by email. About the product: fasteners for headrest are well designed and solid. The main brackets can remain discreetly remains on amounts headrest. The lack of clean battery is handycapant for this material very well made. It also lacks a carrying case. The picture is good, sound enough. The purchase of a separate headset and taking splitter cigarette lighter for GPS and DVD player complete the set.
