PREFACE NOTE: H-D® just released their Boom! GTS system. It uses the same interfaces as their Boom! 6.5GT system described here.

This section is an addendum to the previous article I wrote. Since then I've installed the Sena Freewire™ to enable wireless support of the Boom!™ Infotainment System. Here's what I've found out.

I'd already installed the H-D® CB Module, and the H-D® WHiM, along with it's required additional interface harness. That cable became an orphan, dead-ended in the fairing for now while I installed the Freewire™. I disconnected the WHiM harness and connected the #69200865 Boom! to 7-pin DIN cable because the Freewire™ requires it to talk to the Boom! System. I left it coiled inside the fairing to hide it - the Freewire has a cable that connects to it. I also found a spare 12 volt connector in back of the voltmeter that is hot in ACC & IGN. I tapped into this wire and added a lighter socket for the Freewire's™ power cord. These two connections allowed me to keep most of the Freewire™ wiring out of sight. I then mounted the Freewire™ to the dash panel and ran the wires under the fairing and to those connections.

Once you have the Freewire™ mounted and the connections made, you can follow the instructions on pairing you headset - that part is pretty easy - just set yur headset for pairing mode, and press and hold the center button on the Freewire™ for 5 seconds. It should flash red & blue until it successfully pairs, then flash only blue. Once your initial pairing is done it should automatically pair in the future.

It's always a good idea to make sure your Freewire™ has the latest firmware installed, and this can be done with your computer using the Sena Device Manager" that you'll need to download and install from HERE. Once you've installed the Device Manager software (for Windows or Mac) you can connect the Freewire™ to the computer via USB cable and check to see if your running the latest firmware.

the Freewire™ on my
Street Glide Special.













So how does it work? It works great!... Voice commands work just like the wired headsets, except there's no wires. I have one set of Sena 30K's mounted in my Bell 1/2 helmet, and another set mounted in a Scorpion 1/2 helmet.

Addendum: (sigh - It's always something!) After living with the Freewire™/30K for some miles the quality of the speakers that come with SENA's headsets leave a LOT to be desired. To put it mildly, they suck for anything but standing still with the motor off. As soon as you get going, the engine and wind noise all but drowns out what you're trying to listen to, so you crank up the volume and the speakers go all to hell - and this is on a bike with a stock exhaust system! SENA does include a 3.5mm stereo earbud connector, so the first thing I tried was an old set of earbuds. When you plug them in they disconnect the OEM speakers. Using the earbuds I could hear fine, even at 70 mph, but the eaarbuds were a pain in the a$$. After some research I settled on a set of UCLEAR Digital Pulse speakers, hoping they would sound better. The UCLEAR speakers have the 3.5mm plug that fits the SENA earbud jack. After swapping out the SENA speakers for the UCLEAR speakers the difference was quickly appearent - the UCLEAR speakers were much more efficient (louder) and clearer. I can hear music and voice over the road noise, but nowhere as good as when I was using the earbuds. I guess that's the price you pay for traveling over 40 mph!
