Not sure if this is the right place to post this but here it is. (Apologies if this has been mentioned before but the search button is not my friend - I can never find anything).
Had my 350 a few months and when I bought it I failed to notice the scratches on the sat nav screen. The more I looked at it the more it frustrated. Thought about a new one but around £1300 +VAT. It was not that annoying. When I got it serviced last month mentioned it to the Nissan guy who came and had a look. Informed it was just the anti-glare layer which someone had cleaned with something far too abrasive. Found the following thread on another forum and followed the suggestion.

Used peek metal polish to remove the anti-glare layer and an ipad anti-glare film cut to size and as good as new - actually better anti-glare than the unaffected area was before.
Hope this may help someone else with same issue.
