How to update maps on your Lexus Navigation system

The Lexus Navigation system can be updated periodically using downloadable updates, ensuring that you always have the latest road and route information in your Lexus, saving you time, money and minimising stress when journeying to a new destination.

Updating the maps is a simple process, and you’ve probably got the equipment to hand already – all you need is an internet-connected computer and a blank, formatted 4GB USB memory stick.

To find out how to purchase, download and apply the map update to your Lexus, simply watch the video below or read on for a step-by-step guide.

  1. Begin by taking your blank, formatted 4GB USB memory stick and inserting it into a USB socket on your computer.
  2. In a web browser, navigate to the Lexus customer portal and sign in. If you don’t already have an account, you can register at this point.
  3. Once signed-in, click on ‘e-Store’ > ‘Map & Software Updates’. Click on the price button to get more information on your update.
  4. Identify your car, agree to the terms and conditions, add to your shopping cart, and pay by credit card or via PayPal.
  5. Go to the ‘MyAccount’ page to view your purchased update. Click on ‘MyDashboard’ > ‘Downloads’ where you will see your purchase with three icons alongside.
  6. To enable the map update, click on the key icon. You will be given a 16-digit activation code, which you can write down or print out.
  7. The second icon gives you a set of instructions on how to download and apply the update to your Lexus.
  8. The third icon is a link to the actual download. Download the ZIP file, extract it on your computer and save the extracted file to the blank USB memory stick.
  9. Now take the USB stick and the 16-digit activation key to your Lexus. Plug the USB stick into the USB port of your Lexus and follow the instructions show on the navigation screen.

If you need any help along the way, don’t hesitate to call or pop into your local Lexus centre where a fully trained technician will be happy to help.

  1. A LEXUS 450h is supposed to last more than 14 years …
    DOES LEXUS AGREE OR DISAGREE??
    If agreed, please explain why you do not provide.a CURRENT map update for my late 2009/ 2010 model 450h.
    Thank you.

    1. Hi Peter, thanks for getting in touch.

      We’re pleased to hear your Lexus is doing well, it isn’t uncommon for updates to eventually become dormant for vehicles of a certain age. As the times change so do product offerings and there becomes technological limitations for older models.
      We’ll pass your feedback on this along to our team.

      Thanks

  2. Hi,
    I sent an email some months ago asking about possible map updates for my NX300H 2015 model in the UK.

    Is that possible?

    Thanks

      Thanks,

  3. Hi
    I have a 2023 NX450h with Lexus Link 9.8 inch multimedia screen. Am I correct in thinking that this system does not need to update the maps manually because the TomTom mapping used is updated incrementally OTA by TomTom?
    Thanks

        1. Hi Colin,
          Our Multimedia Team have confirmed that this vehicle has cloud based navigation, it will update automatically twice a month and 24 times a year, you will not need to do anything.
          It’s also not TomTom mapping that is used.
          We hope this helps.
          Thank you.
