Okay, fantastic, the modified version of the script is correct. Without the NAD27 to WGS84 data conversion, the car's position on the map route is perfectly nailed. Fantastic!

Now for the next problem.

Every single turn is wrong. Every single turn tells me (for example) to go left when it's clearly right. Also, as I execute that turn, it doesn't advance me to the next waypoint.

I'm pretty sure this is because the Google Maps data has some kind of a "hiccup" in the data points at each turn location. This happened before when we tried to use another mapping program. instead of a turn looking like this...

Code:

---

|

O-------

If you magnifiy it really small, in the data points it acutally looks like this:

Code:

---

   |
   |
   |
O--|-------
 \ |
  \|
   |

---

Is there any way we can fix that in the script?
