Well, there is another little piece that you have to build to interface with the factory NAv setup, but it's only around $43.00 (according to him). From what I understand, that's all you need. Check Swoobyz's site and it will explain things a little better. He has hooked up an in-car PC so there are some differences, but the final connection to the Factory NAV is the same:
