LOL... That's the database version not the date of the maps. Mine is the same version with a 2015 date for the database.
Do you know if my Prius v4 (July 2017)needs to any head unit update? If so how it is accomplished? Posted via the PriusChat mobile app.
Toyota head units sold in Europe use map and software updates that are different from those in the U.S., Japan, or other regions. If you register your Prius and its navigation system on Toyota’s Customer Portal, you should be able to see any updates that may be available, at no cost or for a fee, and the installation instructions.
