Hiding the user interface (UI) on Google Maps Desktop is relatively easy. First, open the Google Maps Desktop application and locate the three lines in the top left corner. When you hover over the three lines, an options list will appear. Click on ‘Hide UI’ in that list. You should now see a large map display with no user interface, allowing you to concentrate on navigating your route or searching for a particular location. You can always toggle the UI back on by clicking on the three lines again and selecting ‘Show UI’ from the options list.
