How to unlock a Navteq SD card

Updated March 23, 2017

Navteq produces mapping and location data for car navigation systems, internet applications and portable and wireless devices. Various car manufacturers and GPS providers use the company's map data to power navigation systems. This content is typically provided on SD (Secure Digital) cards. If your car’s navigation system does not come with unlimited SD use out of the box, data will only work for the first 600 miles. You will then need to activate and unlock the card for unlimited use.

Find the serial number and serial code

Look at the top right corner of the packaging supplied with your system. Write down the serial number printed there.

Press the “Menu” button on the system to start the serial code process. Select the “Configuration” option and press the control button.

Select the “SD management” option, and then press the control button. Select the “System Serial Number” option and press the control button again. Write down the 11-digit serial code shown on the display.

Activate by telephone

Call Navteq’s customer services hotline -- use 08081 013885 if you're in the UK or 00800 18235322 from the rest of Europe.

Give all information requested to the customer services representative. In addition to the serial number and serial code, you must also provide your map coverage area and contact details. You also have to give your name and address, although you do not have to give an email address. If you choose to give an email, your code will be sent to you as well as given over the phone.

Carefully write down the 16-digit activation code. Go to the Navteq website and navigate to the “Find Your Map” page (see Resources).

Activate online

Choose your car manufacturer to access its account page.

Click the “Sign in” button in the top right corner of the page. If you already have an account, log in. If not, you will need to register.

Look for the “Activate Service” button, and then click “Generate Unlock Key.” Write down the 16-digit activation code.

Activate maps

Enter your 11-digit serial code after registering the device. If you've already registered the device you can skip the initial steps in this process.

Choose a name for the device and type it in before clicking “Add New Device.” Confirm that the default device listed for your brand is correct.

Select “Add New Device” again, and then choose “Add New Services.”

Enter the serial number of the device. Use the drop-down menu to select your map coverage, then click the “Unlock Map Product” button.

Activate and verify the SD card

Insert the SD card into your system and click “Menu.” Select the “Configuration” option and press the control button.

Select the “Map License Activation” option and enter your 16-digit activation code.

Return to the main menu, select “Map Licence Status” and press the control button. A screen should appear showing that the SD card has been activated for unlimited use.


You may not need to follow these instructions each time you add a new map coverage area or map to the system. Keep a note of your serial number, serial code and activation code in case you need them again.


The Navteq SD card is not designed for general media storage. If you use it in other devices or try to add other data, such as music, photos or maps from other systems, it may stop working.
