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. Hello Andrei,
      Thank you for your comment.
      We would recommend taking your vehicle to your nearest Lexus Centre, who will be able to check for updates. They will then be able to book your vehicle in if needed.

      1. Called few places sand some said there are no updates needed and 1 or 2 places said there are uptades. A bit confused now.
        Was thinking that u might know the latest versions and i can compare them with mine.
        Thank you.

  2. What about “Gracenote” database updates? just checked my 2016 IS300H and the database says “1990” The feature allows it to be updated by USB but I cannot see any updates from Lexus/Gracenote.

  3. How can I register my 15cy navigation on My Lexus account? There are 4 options for nav systems and 15cy is not one of them

  4. I have just bought a used Lexus RX350 , model 2013 form USA. I am using this car in Ghana , West Africa. How can I change and Upload Ghana map on my Navigation system

    1. Hello Alfred,
      Thanks for getting in touch.
      Unfortunately, we are only able to advise on UK specification Lexus vehicles.
      We would recommend contacting Lexus in your region.

  5. My Lexus does not have apple play, but is there a way to mirror your phone to the screen in the car?

    My model is the NX 2017

  6. Good afternoon
    Will lexus be bringing a update out for Apple car play & Android Auto as when connected to my new ux for the sat nav the HUD display does not show any sat nav directions.

    I would like to use the built-in sat nav but obviously it can’t compete with Google live traffic information & re routing.

    Kind regards
