Summary: This thing is awesome. Even more advanced than a garmin or tomtom, and it is so much more convenient because I just got the avh-x5500bhs, really nice system. Its nice that all i have to do is press a button on my head unit and im in navigation mode, and I dont have extra stuff impeding my vision (ie. gps unit and mount). Thanks Pioneer! O, and I installed it myself but I have experience with that stuff, otherwise I wouldnt recommend doing it yourself.
