Google Maps will let you navigate as Mario in his kart for one week starting tomorrow, MAR10 Day
But suppose you want to celebrate Mario and not have to shell out any cash to do so? As it turns out, Google has pushed out an update to Google Maps that will replace your location icon with the image of Mario driving his kart. This will be available to Google Maps users for one week only.
To have Mario lead you on your journeys using Google Maps, you will need to make sure that you have the most up-to-date version of the app. Open it, and tap on the yellow block with the question mark inside, located to the left of the Start button. Tap it, and for one week you and Mario will be following the same directions.
