As you can see in the previous image the Turn Preview screen includes 

a close-up map of the turn itself and a magenta route line showing your 

path.  
Additional data boxes show the text instruction, the distance from your 

current location to the selected turn, the direction of the turn (in this 

case a right turn) and the total distance from the turn to the end of the 

route. 
If you want the iWAY to automatically show you Turn Previews when-

ever you are navigating make sure 

 is checked. You can 

turn this feature off by unchecking the box. 

Categories Drawn 
The Categories Drawn command lets you choose how much of the map-

ping detail available in our database you want shown on the screen. 

This information includes contacts, points of interest, cities, highways, 

etc. 
If you draw too much detail the screen can look cluttered. If you don't 

draw enough you are probably not getting the most value out of your 

unit.  
You can use the Categories Drawn command to selectively turn on or 

off any of these items, customizing the map to your needs. From the 

Options Menu choose 

 and a screen like the one in the 

following image will appear.
