The installation looks very easy itself. If I remember right they have very detailed instructions on their site. Someone else did an install of a backup camera and posted a great sequence of pics on how to remove the trim and the NAV unit. After seeing this it made me feel comfortable to decide to do this on my own. I have done a test run on removing the necessary trim...except the vent covers but I feel confident that i can do that. Here is a link to the post.
