      Our line of commercial GPS devices will allow you to use text-to-speech guidance. The GPS systems will allow you to use a touch screen to help navigate you to your destination. All of our devices can be customized to fit your truck’s exact height, length and weight. Unlike standard GPS solutions, our GPS devices automatically create routes that are specifically suitable for trucks, taking into account low bridges, weight restrictions, unpaved roads, or any other route that isn’t suitable for trucks. If the route isn’t passable by truck, that route will appear in pink on your screen to act as a guide. If you must make a local delivery, the driver can choose to ignore the local restrictions as necessary. The driver can easily decipher why a particular area is restricted.

     Yes, you can easily set the WorldNav software to any size weight and height of a vehicle, so the routing can support a car hauler, cranes, and other construction vehicles as well as any size 18 wheeler. For example, if your truck is 13'6" you may want to set your height at 13'9" if there is packed snow or ice on the road so you can be sure to avoid any low bridges.

     The WorldNav software does not attempt to avoid weigh stations however you may use the software to locate weigh stations as you travel.
