Retrofit the rear was done by my VW dealer (they forgot to order/do it in the factory

) it is definitely not as good as factory (as my previous GTI had) and you loose the image on your screen (I have a camera..lucky me).
The standard sound goes like a caged wild canary...so I let it tune down and recalibrate !!!!
They said doing the PDC at the front is impossible....(also factory forgotten)

Positive note:.....with a lot of negotiating they remapped the monster...to compensate for their momentary lapse of reason
