Unless you are using *.spc, you must have speedcam.txt for proggy to convert over to speedcam.scdb for it to use. If the conversion is successful, then you should see icons showed up on map. Alerts will not work in simulation, so you'll have to drive pass it. Sound depends on whether you're using TTS or not. Either case, you have to configure audio files and TTS voice file correctly. Skin is another factor.
