Based on the info above, I did a search for 464.425 on the FCC site for genesee county, only one that showed up was Fenton as shown above.
I also did a full genesee county search and there is no listing showing Lakeville. When that happens, just my assumption they likely have moved to a large trunked radio system, but probably not MPSCS as they have contracted out their radios. Granted there are a handful of schools on MPSCS but the normal route is to go onto a large business radio system. This is where its so advantageous for locals to find out where agencies are and if the database is incorrect, let us know with a submission to update the database.
Other thing is clear, the database thats in your radio currently is out of date and you need to attach to computer and get it updated, including the 668's firmware. Thats where sending it in to whistler to upgrade would take care of those items.
