But when the dealers have something to update in your car software, no matter what part of the car it is, they will upgrade all modules to the latest revision. I am not sure they would even know how to skip one module. They do this because software is integration tested at a common revision, and could have bugs if you mix versions.
The best solution would be if the car owner could overwrite the maps through OBD2 or something. It used to be possible on older BMWs.
