Video-Using the Harley dealership Digital Technician software, we show you how to flash a Boom Box Infotainment System after installing a Wireless Headset Interface Module or “WHIM”. Only authorized dealerships have access to this software. There is a specific process that needs to be followed and particular boxes that need to be checked for a successful flash. After a successful Boom Box flash, you'll have a new menu item in your setup options called “Wireless Headset”. If you see that then you know it was successful.
