Overlay Data Setup 
Overlay Data are the text boxes that appear over your map display con-

taining information such as the distance to your destination and the 

instructions for your next turn. 
You can choose which information you want to display as Overlay Data 

and its location on the screen. To do this, from the Options Menu 

choose 

. The first screen that appears is the Overlay 

Data Shown screen showing your current setup. You can select any 

item in the list to change its font size or location. 

 

You can also choose the last line in the list "Press here to add..." to add 

another data box to your screen. The list of available overlay data ap-

pears in an expandable tree structure. 
Choose the + next to any of the categories to expand it and show the 

available data within the category. You can press the - next to any ex-

panded category to hide its contents and clear up the screen. 
From this list choose any of the data options to add it to your Overlay 

Data. You can then modify it on the Overlay Data Shown screen just 

like any of the others. A checkbox at the bottom of the screen allows 

you to determine whether the iWAY should draw boxes around the in-

formation presented or overlay the text on the map.
