With the Harley-Davidson Audio Interface Kit (Brochure) from Kennedy Technology Group, Inc., a wide array of cell phones, Alert Devices (e.g. radar detector, GPS) and two way radios can be heard in the rider and passenger's headsets.

NOTE: Audio from your devices will not go out over the bike's speakers. It is available only in the helmet headsets.

The photo below shows the system installed with a DualSet for Alert Device audio input, an Intercom Audio Interface for cell phone, and an FRSet for FR/Amateur Radio.

For clarity, the Alert Device, cell phone, radio and power harness are not installed.

This system is not compatible with pre '98 models and Kennedy does not currently offer - or plan to develop - a system for pre '98's
