MARS, er uh, Cody, will strictly give you arrests (whether dismissed or not) on the juvenile and adult level, although you can't give the juvenile information over the air, as well as active and vacated restraining orders. Remember though, if someone is arrested in Passaic county for example, and you are a Bergen county agency, you will not be able to see this lock-up as it will not even show itself in Cody. This goes for all the other 20 counties in New Jersey.
Unlike Cody, ACS tells you if someone is wanted criminally in all of New Jersey. The Automated Criminal System shows pending and active criminal warrants.
Also keep in mind... although many people are still calling it MARS, don't be fooled, as these people don't take to change easily and they are really referring to Cody.
