GPS- Distance and time to destination wrong

If you live in a non metro area or no major highways near by, the car gps is a joke. I just wish there was a way to turn the gps live tracking as your driving so you don’t see the triangle pointer moving on the map.

 

Did you program your home address correctly?

 

What navigation do you have? In the OEM Toyota navigation (like the B9016) there is setting for the average speed on 3 different road types. That might be off. There is also a setting to avoid certain roads, like toll of highway.
Does it give you the correct route but says it is much further? Does it maybe display kilometers and not miles?

 

Is it showing the actual route you take? If not, is your nav system set to avoid certain types of routes?

Are you driving significantly faster than speed limit (or what the limit was back in the few years just before this car was produced)? Or faster than it expects on some certain lower level back roads?

Some of my nav choices (car / Garmin / Google, don't ) will initially pad some extra travel time on to long trips, allowing for some breaks that everybody should be taking. While I usually take even longer stops, extending the total trip time, occasionally I can do better (fewer / shorter stops) and watch the arrival time get significantly earlier throughout the trip. Only some of the systems do this, but I'm not awake enough at the moment to accurately say which. (No, I'm not driving now.)

 

But is the route displayed on the map still correct?

I'm still seeing insufficient clues ...

My OEM navigation does not do that. It calculates time based on the average speed in the settings. Of course when you drive faster, the time goes down more rapidly, but it does not recalculate a new time.

So I ask again: which kind of navigation do you have? There were a few very different navigation units installed in the Prius.

 

Difference such as?

 

This is a tough one. With an 8 year old unit, there might not BE a good fix.

Most are supposed to "learn" your driving habits......speed mostly.....and make the initial calculation based on that.
That wouldn't cause a distance error though.

Check your navigation settings and look for something like "factory reset".
If there is some bad data stored in the memory, that might clear it out.
And no, removing the power won't do the same thing.

I would ask if you have ever updated the map but that can be expensive and might not be worth the gamble.

If it still gives you the right routing directions, it isn't a total loss.
