If you are not a little skilled with Adobe Illustrator you can not do anything. Otherwise, you have 2 possibilities, the first is to replace that image to what's in the file speedcam.zip, (Fix Speedcam). If you have the coordinates only of these radar devices, you can create a new category and replace it to one of the useless ones always in the speedcam.zip file. In the second case you must also edit the lang file for the menus, and the voice file to get the sound alerts.
