Was a little hesitant in purchasing this item since it was the cheapest I could find and that other websites only metioned it was for navigation unlock. But I'm glad I did. Video unlock works awsome. Follow directions and bam your done in 30 minutes. Use double sided tape or velcro to keep the box from rattling around. Also, use volume controls on steering wheel if you don't want your movie to be interrupted. Only a few seconds though.
