The only way I know is to treat school zones as 40klm speed cams.
Setup a .txt file with the school zone info in it in the correct iGO8 format then put it in the speedcam folder. When you load iGO8 it will load that into it's SC database. You need to leave the .txt file in the folder all the time.
If you are also running the Ultra 5.0 skin then you can also set the distances and type of alert that will display / sound etc.
If you PM me I can send my file to you via email it is only 60k.
