Found the external mirror covers pick up brush scratches easily from roadside bushes, over than that all ok.

Easy enough to fit yourself however will still need a dealer visit to update the software

You sure its not the daft collision prevention gubbins?
We had similar and only way to cure it was to lower sensitivity of the system and ultimately a software update from the dealer.

I had it in my Tiguan ad couldn't get on with it. It messed up my phone calls. Hence didn't specify it in my XC40. I plug my iPhone in (and hence charge it as well) and can then play what I want - music or usually podcasts from the screen without having to look at or touch iPhone. I am sure you can...

At first I thought it was a total shed to drive with poor gear changes and terrible changeover however after complaining to my dealer they uploaded the latest software which made it far better, ...
