To update a Toyota navigation system, purchase a navigation update through a Toyota dealer. A dealer locator tool is available on Toyota.com, as of 2015.
Toyota typically updates its navigation software in the fall. Always consult a dealer before purchasing a navigation update, as it may not be necessary depending on your driving area, especially if you don't live near a population center.
To use the dealer locator, visit Toyota.com, and click Find a Dealer. Enter a ZIP code, city and state into the search bar, and perform a search. Alternatively, enter the name of a dealer.
The tool lists nearby results and displays them as icons on a map. Each list entry provides the dealer's name, address, hours, phone number and special features, such as associates who speak Spanish. Entries also provide links to each dealer's website.
Click Dealer Details for more information about a dealer, including a description, its awards and phone numbers for each department at that dealer.
Toyota vehicles use a navigation system called Entune. Multiple feature packages are available, and Toyota also offers an Entune smartphone application. Entune uses touch-screen controls, but hard-button controls are also available. It has multiple menus, including a home screen and applications screen.
