How do I update my Lexus navigation software?

Update your Lexus navigation by downloading the latest map update from the Lexus Owners portal to a USB drive and installing it in your car, or by using available over-the-air updates if your model supports them.

Update availability and steps vary by model and region. This guide explains how to check your system, prepare files, and complete the upgrade, with troubleshooting tips.

Update options for Lexus navigation

There are two main paths to bringing your maps up to date: USB-based map updates from Lexus and, on newer vehicles, wireless updates delivered through the built-in connected services or the Lexus app.

• USB map updates from the Lexus Owners portal


• Over-the-air updates via the built-in system or Lexus app (where supported)

Note that availability depends on your vehicle's year, region, and multimedia system. Always check the official Lexus update page for your exact model.

USB map update: step-by-step

Follow these steps to update via USB, which works for most models and regions.

1. Confirm your vehicle supports USB updates and identify the correct region/version by checking Settings in the navigation system or the latest update notes on the Lexus Owners portal.


2. Visit the Lexus Owners portal, sign in, and navigate to Navigation/Map Updates. Download the latest map data for your vehicle to your computer.


3. Prepare a USB drive formatted as FAT32 (or as required by Lexus) with sufficient capacity, and copy the update file(s) onto the drive according to the portal instructions.


4. In the car, insert the USB drive with the ignition on; follow the on-screen prompts to install the update (Settings > Map Update or similar). Do not turn off the vehicle during the process, and allow it to complete.


5. After installation, verify the map version in the navigation system and remove the update file from the USB drive if directed by the on-screen prompts.

Keep in mind that some regions require specific folder structures or multiple USB drives. Always follow the official update guide for your exact model.

Over-the-air updates (OTA)

Available only on select models that support OTA map updates via connected services or the Lexus app. Here’s how to check and install if your vehicle supports it.

1. Check whether OTA updates are available for your model in Settings > Map Updates or through the Lexus app. Confirm your vehicle has active connected services.


2. Ensure the vehicle is parked, and follow any prompts regarding power and connectivity before starting the update process.


3. Initiate the update from the in-car prompt or the Lexus app; the update may download and install automatically when conditions (power, connectivity) are met.


4. Once complete, verify the new map version in the navigation settings. If issues occur, retry the update or contact Lexus support.

OTA updates can be convenient but depend on model compatibility, region, and active connected services.

Summary

Keeping your Lexus navigation current improves route accuracy and coverage. USB map updates from the Lexus Owners portal are widely supported and reliable, while OTA updates offer convenience on newer models with compatible connected services. Always verify your vehicle’s compatibility, use the official Lexus portal or app, and follow the prompts carefully. If you’re unsure, your local Lexus dealer can perform updates or provide guidance.

How do I update the software on my Lexus?

You can update Lexus software either automatically through an over-the-air (OTA) update via Wi-Fi or by manually downloading the update onto a USB drive. To check for an automatic update, go to Settings > Software update on your multimedia display, or check the Lexus app for notifications. For a manual update, visit the Lexus software updates website, download the file, transfer it to a USB drive, and then follow the instructions to install it in your vehicle. 
Method 1: Over-the-Air (OTA) update
This method is for newer systems and can be done automatically or on demand. 

1. Enable notifications: In your vehicle, go to Settings > Notifications and ensure software update notifications are enabled. 
2. Check for updates: Periodically, you will see a notification banner appear on your multimedia screen when an update is available. 
3. Connect to Wi-Fi: For an on-demand update, ensure your vehicle is connected to a private Wi-Fi network. 
4. Navigate to update menu: Go to Settings > Software update. 
5. Install the update: If an update is available, select Update software to begin the installation. 
6. Complete the installation: The update can take up to 45 minutes. After it finishes, turn your vehicle off and then back on to complete the installation. 

Method 2: Manual USB update
This method is for vehicles that do not support over-the-air updates, or for map updates. 

1. Prepare a USB drive: Get a blank USB 2.0 flash drive with a capacity of 2GB to 8GB. 
2. Download the update: Go to the Lexus software updates website and use your VIN or vehicle model to find and download the correct file to your computer. 
3. Copy to USB: Copy the downloaded file(s) to the USB drive. 
4. Start the engine: Park your vehicle in a well-ventilated area and start the engine. 
5. Insert the USB drive: Plug the USB drive into the vehicle's USB port. 
6. Access the update menu: Navigate to Settings > General > Software Update on your multimedia display. 
7. Install the update: The system will detect the new software. Select Update or Update Software to begin the process. 
8. Finalize the installation: Once the update is complete, turn the engine off and then start it again. Remove the USB drive.
