My car was towed in twice (new 2017 MS) during the "Parking Break Needs Service" plague... each time it was towed it never updated the GPS. During one of the long tows I was nervous the car was not yet picked up (since I left it in a parking lot). The Roadside service line informed me that the cars GPS does not update while it is in Park, only when the car is taken out of park will the GPS Update.
Seemed odd to me that this would be the behavior, however seemed to be true on both occasions.
