To update your firmware, you'll first need to connect your Road Scout to Wi-Fi as per page 15 of the manual: HERE. Note that to perform updates, the Road Scout must be in "iRadar Wi-Fi Mode" which can be achieved by holding the BRT button on the unit. If, when holding BRT your unit states "Camera Wi-Fi Mode", simply hold the BRT button once more to return to "iRadar Wi-Fi Mode". 

Next, enter the Road Scout preferences menu by pressing and holding the SEN and BRT buttons together, per instructions on page 9 of the user manual. Navigate settings by rotating the volume wheel left or right to change selections and settings, and using the MARK button to confirm your selection of a category or setting change. To exit the settings, touch nothing for a few seconds and the Road Scout will automatically return to the default functionality.

Hold SEN and BRT at the same time to enter the Menu. You'll see a "Radar" and "CAM" category. Use the volume wheel to ensure that "Radar" is highlighted in white. Press MARK.

Next, use your volume wheel to scroll through the options until you find "Update". Press MARK to confirm, then turn the scroll wheel until the option beneath it says "Firmware", and press MARK again. It should update. Follow the prompts on the screen.

If it says "No Wi-Fi Connection" let the camera return to its default state, then revisit the instructions in the manual on page 15 to ensure you are connecting to the proper Wi-Fi network. Please note that the Road Scout is only compatible with a 2.4GHz Wi-Fi network. If, during the initial connection process you receive an "Unable to connect" message, you are likely attempting to connect to a 5GHz frequency, which will not work. If you have a dual-band router that offers both frequencies, you may need to contact your vehicle or router's manufacturer, or your internet service provider for help on creating a 2.4 GHz network connection that your Road Scout can use.

Once you have successfully updated your Firmware, you can check your firmware version from the settings of the Road Scout itself by finding the Radar setting that says "Version Information".  Alternatively, you can put the Road Scout back into CAMERA mode by holding the BRT button, connect to the "Road Scout" network in your phone's Wi-Fi setting page, and launch the Drive HD app. Check your version number under the settings.
