Physically it will fit as a direct match. The physical changes are the accents are changed from Silver to black. The wiring will not work though. The 11-15 uses a CEGA 1.2 network. The 16-19 Uses a CGEA 1.3 network and the modules will not work in them if mixed. The rear controls are CAN based on the later models whereas the earlier ones are not. This may not matter much since you have a PIU but if you ever want to wire up what's in it than you will need to know this.
