Mine came on the lower setting and I rode it home 72 miles and thought I was getting buffeting around my head. I changed it to the higher setting, very simple four screws and it’s brilliant, the best screen I’ve ever had on a GS, this is my 5th.

Higher position is perfect for me ( 5’10” tall).
Must admit mine was fine in the lower position as delivered, I took it off to fit my powered TomTom support and put it back on in the high position just to try
