Mercedes Benz now using what3words
what3words is a clever location identifier. The new IOS app 3wordphoto allows one to add precise location info in a number of formats.
I added this photo of the new bridge at Boulters to the 3 word photo app. When I share the photo from the app I can either use the what3words map or use the associated references in my sat nav.
