Initially, MSP got funds (probably a grant) to install a receiver in at least one car at every post. There was also a grant to provide one receiver to every Sheriff's office in the state, & additional units for police departments of metro areas (Kalamazoo, GR, Lansing, Battle Creek, Benton Harbor/St. Joe, etc). As older patrol cars were retired & new ones bought to replace them, I'm not sure the receiver units continued to be moved. It's been a while since I saw a car in my county with a LoJack receiver in it. I'm not saying they aren't still out there, but maybe not as prevalent as they once were.Does many cities in MI use lo-jacking?
