I have been researching gps units for some time now. I have been told by many people garmin is the only way to go. I took there advice and bought the c330. I do alot of driving and it works great even when i make a wrong tun it corrects my mistakes and puts me back on track. I work for direct tv so I travel all over lost with out it. It is so easy to use the instructions were never read. I pulled it out of the box and starting using it right away. love the fact that it upcomming streets when your driving and have no set way point. The features I like the most is I never have to look at a map again. It has listing for stores, restraunts, gas stations, ans about anything you can think of. It's like having the yellow pages on you dashboard. when searching for place it not only takes you there it shows you the address and phone #. I also love the touch screen it make for easy use. Two things I wish it had was traffic and weather alearts. Over all for the money it is a great product I would buy another one in a heartbeat. My father uses a garmin for hunting. One day he left it on the roof of his truck, and when he found it it was ran ov over by a car. So the next day he bought another. Garmin is the best for quality and price. I also talk to a few of my coworkers that have gps on the their trucks, one has a tom tom he like it ok but wishes now he bought a garmin after seeing it in action. THE GARMIN C330 IS THE BEST UNIT FOR THE MONEY. GOOD LUCK HOPE YOU BUY ONE TOO YOU WILL LOVE IT. Any questions about the garmin c330 I will be glad to answer them the best I can.
