This is how I understand driver alerts work; there are two modes: prewarn (icon is B&W) and warn (icon is color). Prewarn distances can be set. Warn is fixed (exact sign) location. It's behaving as it's designed. Under NextGen, I have options to set the prewarn distances for 4 different classes of driver alerts: Curves and Corners, Lanes and Overtaking, General Warnings and Traffic and Crossing. This is done under Settings->Warnings->Road Signs. Sorry I don't remember where to set this under iGO/Primo because I don't use it now. You can also modified the distances under sys.txt
