Before starting - there are several requirements needed to ensure a successful software upgrade via USB:

Note: If you don’t have a laptop, you will need to remove Highway’s antenna from your windscreen and upgrade the software using a PC running Windows 7 8 and 10.

Mac OS systems are not supported in this process.

OK that’s the checklist done. If you have all of the above in place then you should have no problems upgrading the software on your Highway.

Let’s get started

Open the web browser on your laptop and click on the link below depending on which Highway you have:

Highway 400:

Highway 400 Antenna V2.2

Highway 600:

Highway 600 Antenna V2.2

Please download and run the exe file.

You will see the screen below (Image 1).

Disconnect the USB cable from Highway’s power adapter and plug it into an available USB port on your laptop.
Next, you’ll need to put your Highway into USB mode. On Highway’s wireless controller, press the Home button and turn and press the Select dial to choose ‘SETTINGS’ > ‘USB UPDATE’ > Confirm by choosing ‘YES’.
