This is very easy to use, especially for those who may be technologically challenged. The buttons on the touch screen are big and clear and its easy to navigate through and use.It comes with a car charger so you never have to worry about it dying while you're on the road.
Its got great search features - you can find stores, restraurants, nearby banks and gas stations with ease. You can select travel routes based on factors like time, distance, and so on as well.
One problem I have with it from personal use though is that on rare occaisions it can be a bit buggy with directions. It'll take you in circles or tell you that you've arrived at your destination when you're not near it. But again, its very rare.
Sometimes it doesn't give you the most notice when you have to make a turn and the pronunciation for it is loud but sometimes not clearly voiced so you need to look at the screen from time to time to verify things.
You can pre-program popular places you go so you don't have to input the address each time.
Since there are popular, be careful not to leave it on your dashboard or seat when you exit your car because thieves will break in to grab it.
For its price and minor flaws, I say this is an amazing asset to drivers. If you're looking ofr a good bargain on a GPS system, this is the right one for you.
Update On Aug 02, 2009: Last weekend my family and I took a trip from NY to NJ using this to find out way to my aunt's house. It got us there quick and easy with no errors whatsoever. On the return home, we got home so fast, my aunt was surprised we made it back so early. So this is a great product!
