Hi, from 2017 onwards VW face lifted the Mk7, most people brand the car with these factory fitted extras as the Mk7.5 version. Included were upgraded headlights, taillights. virtual dash cockpit which I love, and the infotainment, but to answer your question these are factory fitted not retrofitted by myself, there are companies online that retrofit these though.
@@loyalty786 came standard from the factory with them mate, if you run a check online on a 2014/15 model then a 2017/18 model you’ll see the differences 👍
