Connect Nav (NAC) Installation Guide


A key capacity of at least 16GB is recommended.

The USB flash drive must be empty and in FAT32 format. If you are not sure, here is the procedure to format your USB drive in FAT32 format:

CAREFUL Formatting your key will erase your data initially present on that key. Remember to save them on another medium if you want to keep them.

For Microsoft Windows users:

  • Insert the USB flash drive into your computer.
  • Launch File Explorer (simultaneously pressing the "Windows" and "E" keys).
  • Right-click on the affected removable disk and then left-click on "Format".
  • Choose "File System" = FAT32 (default).
  • Left-click on "Start".

For Apple Mac users:

  • Insert the USB flash drive into your computer.
  • Launch the "Disk Utility" application which is located in the "Utilities" folder of your "Applications" folder.
  • Select your USB drive in "External".
  • Choose the format "MS-DOS (FAT)" and the schema "MBR Master Boot Record".
  • Left-click on "Erase"

Note : The 'system' files generated on the key by Apple when you insert it into your Mac may disrupt the subsequent installation in the vehicle. To get rid of it, we recommend that you install the CleanMyDrive utility, available for free on the App Store

To update your system software, you need to download 2 files:

  • The software update, which is compressed to the format .tar:


  • The license file, which has a *.key extension:



The time to download these files to your computer can last from a few tens of minutes to several hours depending on the characteristics of your Internet connection (Hardware, speed).

If you are having trouble downloading this to your computer, you can refer to the following helpers:

Once the files have been downloaded to your computer, you need to extract the files from the file .tar to copy to your USB flash drive.


Here's how to extract the necessary files from the .tar file that you downloaded to your computer:

For Microsoft Windows users:

  • Right-click on the file and select your extraction tool (example: '7 Zip' or 'WinZip') and click 'Extract here', in order to save the extracted files to your computer.

If you do not have an extraction tool, we recommend that you install the 7-Zip tool on your computer beforehand.

For Apple Mac users:

  • We recommend using the 'The Unarchiver' app, available for free on the App Store (

This operation will have generated on your computer a 'SWL' folder containing the update file, as well as an 'UpdateInfo.xml' file, which you will not need afterwards.


You must now copy the extracted files to your USB flash drive:

  • Copy the extracted 'SWL' folder to the USB flash drive.
  • Create a 'license' folder on your key (strictly respect this spelling) and copy your license file into it in *.key format.

The tree structure of your key must then conform to the following:
