Having GPS guidance in the truck opens doors to solving manpower challenges. Is part of your crew out with the flu? Simply attach the GPS enabled device to your windshield, select the route to drive, then follow the path laid out.

Is there a special road hazard, maneuver method, or note a new driver should be aware of? If so, they can be loaded into the device in advance, and appear on screen upon approach.
