"No action has (yet) been assigned to ..... No plugin has assigned itself to the button, or you may have gone on duty twice - make sure only to go on duty once."
If you have gone on duty twice PoliceSmartRadio stops functioning correctly, just quit the game and restart. (To prevent it you have to restart the game before going on duty again.)
Ok, I've made a standalone version of PoliceSmartRadio for those who don't use Traffic Policer or other plugins by Albo1125.

Scroll down the page for the Readme, there you'll find instructions and a download link.

@Demuth I know this has been asked before, but would it possible to make a version of SmartRadio which runs without Traffic Policer?
Is it really dependent on the Traffic Policer.dll or is it just a check at startup of SmartRadio (like Arrest Manager)?
