Regular updates are particularly important for drivers who frequently travel in new areas or rely on the navigation system for daily commutes.

Preparing for a Navigation Update

Before starting the update process, preparation is key:

1. Power the vehicle: Keep the ignition on or the engine running during updates to prevent interruptions.

Downloading the Update

Toyota navigation updates are available through the official Toyota update service. To download:

1. Insert the SD card into your computer if your system uses one, or connect your vehicle if the update supports USB transfer.
2. Select the vehicle model and year to access the correct update files.

Verifying the Update

After installation:

• Check the navigation settings for the current map version.

These steps ensure the navigation system is functioning correctly and contains the latest maps and data.
