anyone know what those yellow boxes are that u see on the screan like when u are in route to a destiantion...are they suppose to represent traffic lights?

 

I believe the yellow boxes are points where you're going to make some sort of a turn

 

The boxes represent the next spot where you will receive instructions.

 

Those yellow boxes are a check points for the GPS. It checks at that point to see if you are on track. If you are not then it will laert you. Also, once you pass this point, software gets the next step up in the direction list.
