Not sure of the specifics on certified installers, but I do know that the state of Florida is enforcing a fine on inadequate record keeping of customer info.. Basically every shop has to fill out a bunch of BS (VIN, tag number, address, vehicle condition, etc. etc. etc.) for every car serviced and store those records. There's some rediculous find (like $2,000 or something) for every car that was worked on missing it. One of the SA's in north FL just got nailed for it.
