Upgrading to the 21 tow mirror with surroundview

[Shaun01]

U will need the cvpm for a 21 to stitch the images right also the application version of the radio needs to be 39.7 or higher I battled for a month trying to get mine to work did everything finally gave up and went to dealer to update radio I was on 34.2 and that did it all works as it should I am now running 40.1

So if you already have surround view on say, a 2019, youll need a different module along with the mirrors themselves. (Am running 40.1 already on 12")
