This is a very GPS unit, i personally own 2. It is a great price and has many usable functions. The GPS works perfectly, gives you your speed which i found to be accurate to within about 1 MPH, and longitude and latitude as well as the time and the number of satalites that you have with a signal. The GPS part works pretty well all the functions work great especially the POI search. It also has a Video player which gives off a pretty good picture as well as has a MP3 player which can plays flawlessly. I can even plug my Ipod into it and play music from that. It has a built in radio tuner so you can play music through your sterio system. Personally the radio tuner is the best i have used so far i have owned 2 from best buy a $20 one and a $70 dollar, i found that those worked the same and the cost of the $70 was way to high. Touch function is very good and you get a giant 7" screen for under 300 bucks hard to beat.
