Route Instruction Format
The route instructions are cryptic to save space. The general form is:

• "Turn no" is keyed to a location on the map so you can tell where you are on the route.
• "R@" or "L@" means turn right or left at the named road.
• "To" means that the route change will be straight ahead (e.g. crossing a county or state line).
• "Leg(mi)" are rounded to the nearest tenth mile and represent the distance to the next route change. This is your "navigation bible". Leg values preceded by a "~" are estimated, so pay attention to the road signs at intersections.
• Occasionally, the road name is preceded by a "T:" signifying a "T" intersection, so you don't have to monitor the odometer on that leg.
• Stops at intersections aren't indicated, nor are turns at intersections that don't require a route change.
• "Trip Odo" is approximate, since errors will accumulate from detours, gas stops etc.
• "Stops" are occasionally included in the route instructions to indicate a scenic overlook, good food or other tourist attraction on the route.
