Also given guidance to have your hands in clear sight when the officer approaches the car, as they know because the tie between your license registration info and your CPL that you car has a CPL carrier in it.
Since it is somewhat tied to the car, when I loan my cars out to folks, I make sure they know to have their hands in clear sight, and inform the officer that they do not have a CPL or weapon.
Honestly I think the guy screwed up.
First if I travel in another state or through one, I have to adhere to the reciprocity agreements with my home state CPL laws. It is my responsibility to know that.
Second, even if I was not carrying, if I were pulled over in any US state I would have my hands in clear sight, explain that I have a MI CPL and whether or not I have a weapon/s in the car.
