<p> CUSTOM MOTORCYCLE CABLES www.hdbomm.com</p><p>The HD Bomm is a hard wired Harley Davidson helmet microphone to GPS microphone input interface device. </p><p>The HD Bomm isolates and seamlessly routes the audio signal created by the driver’s helmet mounted Harley or J&M microphone to the audio input of your Road Tech, Garmin Zumo 550/650 or Garmin Nuvi GPS’s audio input port.</p><p>This allows you to talk on the cell phone that is paired with the GPS’s Bluetooth connection between the GPS unit and the cell phone.</p><p>The Audio output of the GPS must be connected to the Aux input port of the Harley’s Radio in order to hear the caller. This port is located on the lower right front of the Radio which is covered by a rubber plug. If you wish you can modify the radio and add an additional Aux input port to the back of the radio, this cleans up the installation.</p><p>The HD Bomm does not use a switch as other interfaces. Once you initiate or receive a phone call via the GPS interface just talk in a normal voice, no switch to trigger.</p><p>Unlike other interfaces the HD Bomm comes with every thing you need to connect the interface to the bike’s audio system and the GPS you do not need to purchase additional harnesses.</p><p>The HD Bomm sells for less then 50% of other interfaces and only has 2 wires to connect.</p><p>Thanks for looking.</p><p>James Bissonette </p>
