Summary: I do not know how I managed to drive a truck without using commercial GPS. I purchased WorldNav on line and glad I did it. Screen is big and device looks rugged. Speakers are loud and routing is so far been great. I travel a lot and having this type of GPS is essintial.
Summary: I purchased my system almost 1 year ago. I think that my knowledge of roads in US is not very good. The WorldNav GPS system was a godsend to me. On many occasions although it did not route it the way I thought it was right I followed it to find that suggested route is actually better.
Summary: im a commercial truck driver that delivers hazardous materials. I bought this product thinking it would help, but became a total nightmare. The minute I received the gps the sd card was corrupted so they needed to send me a new one. The device is extremely slow and is not accurate at all.
Summary: Any trucker that used this would toss this out the window so fast. Very unreliable. Very primitive graphics, truck routing is pretty much a gimmick. Any road that is not assigned a number designation is considered a restricted route. This is unreal and criminal if you ask me.
Summary: I got this unit to drive my semi. Routing is excellent around Chicago and Indianapolis. I have this GPS for several month now. I love big screen. I used to play with Garmin and I could not see much. I do not use this GPS for movies or for reading books.
Summary: Teletype 720060 7-Inch Worldnav Truck Portable GPS Navigator We thought we'd done our research, and chose to believe the positive reviews (about 50%) Big mistake. The graphics are primitive and dark, it's difficult to leave the map, do some searching and return to the map without potentially losing...
Summary: The Worldnav Teletype 7200 series is a great idea. It is way over stated by the manufacturer. If you haul hazmat or over sized loads, this unit "may" be of benefit. Otherwise, go with a better known more feature packed unit like the Garmin or high end Magellan's.
