 While there are plenty of options for truck routing GPS devices, some are definitely more popular than others. Some key features users should research about any GPS, especially trucking navigators, are: 1. Coverage area - Detailed maps covering a driver's entire travel area is imperative. Since maps should be updated on a regular basis, the cost of these updates is something to keep in mind. 2. Ease of use - A user-friendly menu is a definite plus. Drivers have schedules to keep so they don't need to waste time figuring out how to input data. 3. User-specific data - Some devices offer the option of entering the exact height, weight, and length of the vehicle. These details, along with the number of axels per trailer and whether the load contains hazardous material, are essential for deciding which route is best. 4. Logging drive data - Users can keep a record of distance traveled and fuel consumption right on their GPS. With Fuel Logs, the driver can enter in the exact price of gas when filling up, and some units will automatically calculate the mileage report. 5. Trucking Routes - All truck routing GPS units should take into account the type of road - residential, commercial, hazardous goods route, or main and secondary highways. Many large vehicles cannot take sharp corners or u-turns, so drivers need a GPS device that will assist them in avoiding these situations. Additional benefits would be low bridge warnings and advanced lane assist notifications. Garmin and TomTom are two well-known manufacturers of truck-specific navigators. Garmin carries the nuvi 465 and dezl 560 models which are popular within the trucking community. As for TomTom, they recently introduced the PRO 7150 TRUCK GPS to try and compete with Garmin's highly successful models. |
