How do I update my Lexus multimedia system?

To keep your Lexus multimedia system current, you can use over-the-air updates if your model supports them, or perform a USB-based update downloaded from Lexus’s official site, or have the dealership handle the installation. The exact steps depend on your model year and feature package, so consult your owner’s manual or Lexus support for the correct file and procedure.

Update options

There are two primary pathways for most Lexus models: over-the-air (OTA) updates that install automatically or on request when the car is parked and connected, and USB-based updates that you install manually using a file downloaded from Lexus's official site. Some models also support update prompts via the Lexus app, or you can rely on a dealership for assistance.

Over-the-air updates (OTA)

OTA updates can download and install remotely on vehicles that support the feature. The process typically requires the car to be parked, connected to a stable data network, and have sufficient battery power. Here are the common steps you’ll follow:

• Verify your vehicle supports OTA updates and that you have an active data connection (built‑in cellular link or a connected Wi‑Fi hotspot).


• In the car, go to Settings > System Updates (or check via the Lexus app if supported).


• Tap Check for Updates and follow on-screen prompts to download and install. Do not power off or drive during installation.


• After installation, the system may restart. Confirm the update version in Settings.

OTA updates are convenient and can add features or fix issues without a dealer visit, but availability depends on model year and trim. If you don’t see an update option, your vehicle may not support OTA updates yet.

USB updates (maps and system software)

USB updates involve downloading the correct file from Lexus’s official support site and transferring it to a USB drive. This method is commonly used for navigation map updates and, on older models, for core system software. Typical steps include:

• Identify your exact model year and trim to locate the correct update file for Navigation maps and system software on the Lexus support site.


• Download and, if needed, extract the update file on a computer.


• Copy the update file(s) to a USB flash drive formatted as required (commonly FAT32/exFAT) and remove other files.


• Insert the USB drive into the vehicle’s USB port and access Settings > System Updates > Update from USB (or a similar option).


• Follow on-screen prompts to install. Do not remove the USB drive until the update completes and the system reboots.

USB updates are reliable across many model years, but you must use the exact file designed for your vehicle. Installing an incompatible update can cause issues with the multimedia system.

Preparing your vehicle for updates

Before starting an update, ensure you meet safety and readiness requirements to minimize the chance of interruption or damage to the software installation.

• Park the vehicle in a safe location with the engine on or in Park/Accessory mode, and engage the parking brake as required by your model.


• Ensure adequate power: keep the battery charged or the engine running to avoid power loss during the update (aim for at least 50% charge).


• Confirm a stable data connection for OTA updates (built‑in eSIM, in‑car Wi‑Fi, or a reliable mobile hotspot).


• Double-check you have the correct update file for your exact model year and trim if performing a USB update.

Proceeding without sufficient power or connectivity can interrupt the update and potentially affect system stability.

Where to find updates and help

Updates and support resources come from several official sources, plus dealer assistance when needed.

• Lexus official Support site: Look up your vehicle’s year/model to download OTA update packages or USB update files, if offered for your configuration.


• Lexus Owners app: Some updates, prompts, and notifications can be managed through the app on supported models.


• In‑vehicle settings: Use Settings > System Updates (or similar) to check for OTA updates directly in the car.


• Authorized Lexus dealership: If you’re unsure, cannot locate the correct file, or encounter issues, schedule a service for installation and verification.

After the update completes, verify the new version in the system information panel and test core functions like navigation, media playback, and voice commands to ensure everything runs smoothly.

Summary

Keeping your Lexus multimedia system current typically involves OTA updates where supported, or USB-based map and software updates downloaded from Lexus’s official site. If your model lacks OTA capability or you prefer professional care, dealership services are available. Always prepare with a charged battery and a stable data connection, and use the correct file for your exact vehicle. Regular updates can improve navigation accuracy, performance, and security while introducing new features.

Can I update my car software myself?

Yes, you can update your car's software yourself, especially for newer vehicles that support over-the-air (OTA) updates via Wi-Fi or a built-in data connection. For older vehicles or certain complex updates, you may need to manually download files to a USB drive and install them, or even take the vehicle to a dealership. 
Over-the-air (OTA) updates

• How it works: Many modern cars automatically download updates when they have a connection, and you just need to follow the on-screen prompts to install them. 
• Requirements: You will need a strong Wi-Fi or cellular connection, so avoid parking in underground garages or covered areas where the signal may be weak. 
• How to check: You can often find the option to check for updates in your vehicle's infotainment system under the "Settings" or "Vehicle" menu.

Manual updates via USB

• How it works: Some manufacturers allow you to manually download an update file from their website to a USB drive and then install it in your car. 
• Requirements: You will need a USB drive of the correct size (often 32GB or larger) and your vehicle identification number (VIN). 
• How to check: Visit the manufacturer's support website for your specific model, enter your VIN, and see if a manual update is available.

Important considerations

• Installation complexity: Some software updates are highly complex and may be best left to a dealership to avoid potential issues or damage to your car's systems. 
• Free vs. paid: Some updates may be free, but it's important to check your warranty or service plan, as some manufacturers may charge for certain updates, especially if they are a few years old. 
• Check with your manufacturer: The best way to determine if you can update the software yourself is to check your owner's manual or visit your manufacturer's official website to see what options are available for your specific vehicle.

Can I upgrade my Lexus infotainment system?

Because the infotainment system is also tied into several of the car's other systems, it also means you can't even update the hardware as it won't talk to the rest of the car properly.
