I had my brother install it in under three hours (was his first time). The system is user friendly. What I love the most is that you can run the GPS and listen to music at the same time. The music lowers a little when the voice comes on to instruct you where to turn. It requires a "mouse like" device to be placed in the corner of the dash that works with the GPS component. It has an AMP built in the music is loud and great. I initially needed to troubleshoot because the radio was a little staticky at first. All in all I love it! By the way you have to buy an install kit (Double Din) which I purchased for a few bucks on Amazon as well.
