I tested the device here in Hawaii and while some will say why test a GPS in Hawaii, I had a specific mission in mind when I tested this unit. First of all the traffic is really bad at times so I waited till it was one of those days in gridlock when I employed my strategy.
This GPS comes with the ability for it to look ahead and give you some alternate routes. So I followed the alternate routes that the GPS gave me in my time of need and found some back streets the locals knew well but not having been born and raised here I did not know about.
Much to my surprise more often than not I was able to get ahead of the traffic by using back streets it routed me to which was good considering the price of gas here.
Second thing was I wanted to test usability and I found that the device was easy to navigate with one exception. The map zoom features really drove me crazy. Two small icons in the touch screen caused zoom in and zoom out. Often the zoom feature would only hold a few minutes and resort back to a wider view which I did not care for.
The GPS Unit seemed forever to pick up a GPS signal even in clear skies and the unit had a tendency to reset itself whenever I restarted the car which was annoying. Overall my impression on the route around feature was good but sadly I cannot recommend this unit as a product to purchase largely because of the zoom feature controlled on screen. The folks at Goodyear need to go back to the drawing table on this one.
Note: I was provided a unit to test and tested this unit in real world conditions for 7 days.
