07 prius package 5 nav

There is on the 2 Lexus I've had.

Zoom out on the display to see the entire route. I have had no seriously wrong directions on my Lexus nav system.

Yes, there is a detour option. When the route guidance is operating, hit the "Route" button, and then the "Detour" button. Then you can choose 1 mile, 3 miles, 5 miles, or whole route.

(Yes, I know that the separate Navigation Owner's Manual (separate than the regular Owner's Manual) can be hard to read, but I highly suggest putting aside some time to flip through it. Hopefully your dealer remembered to give one to you when you bought your car.)

Did you perhaps set your Prius navigation to avoid toll roads or highways, or have you set any areas to avoid? That could be causing some of your routing problems.

For a generic idea of the chosen route, when setting your destination use the "3 routes" button to give you the "quick 1/2, short" routes, and then you can pick which one you want, rather than just going to the fast "guide/route" button.

I haven't played with the Gen5 navigation, but the Gen4 allowed you to use the Map View switch, and choose a route preview option (which will show a dot moving along the map showing you the route), or a route overview option (which will let you scroll through a turn list).

Gen5 Navigation tutorial (for a Lexus, but same as on the 2006-current Prius):

I will insert that you cannot do accurate individual tank-to-tank mileage calculations on the Prius (in the USA anyway) due to the flexible bladder that may not always "inflate" fully when refueling due to temperature, nozzle position, car inclination (sloped ground around pumps) and the condition of the pump nozzle. If the nozzle is scratched or dented it may not make a proper contact with the rubber seal in the car's filler neck and a good seal is needed as the Prius tank uses the pressure from the pump to help fully inflate the bladder. A more accurate method is to simply start recording total miles and total gallons pumped over as many tankfulls as possible.
