The connector to the HD's audio system at the headset port is either a 7-pin DIN or a 5-pin MIDI plug. I gave up trying to solder little wires to the 7-pin DIN plug; kept getting the pins too hot. Now, I just use a MIDI plug with the cable already connected. Much easier to deal with. Doesn't matter that it's only 5 pins; the missing pins aren't used anyway. You can get a MIDI plug/cable at Radio Shack, 2 for about $8. The Sena helmet clamp is a A0304; costs about $35.

Another way to connect to the HD's audio system is via a 12-pin Deutsch plug (part numbers listed in circuit diagram) that connects to the bike's Audio Overlay harness at a plug under the tank. This method of connecting is out-of-sight, very elegant.

 

Are there any "off the shelf" female type connectors that marry up to the male conector that comes off this Sena headset clamp? Seem proprietary but, just wanted to be sure before I hack something up to work.

 

Yep, it's proprietary; no off-the-shelf plugs available. I cut the cable/plug off one of the 2 mics (1 shown in your picture) that come with the Sena helmet clamp. Then, solder the wires of the cut end of the mic cable to the appropriate place on the board. These wires are 2; a white insulated wire (signal) and an uninsulated shield (ground).

 

Any news on a production run? I just can't seem to find the time or patience to even try and make my own...

 

I decided I didn't like the SENA proprietary mic and wired up a radio shack 1/8" female mono cable in its place right onto the SMH10 clamp (See images below). 1/8" mono male cables will be what I run to my saddle bags so I have the options of doing something like a flush mount using audio couplers etc. Thoughts?

 

John, does the new 787 headset sound much different from my current ECD-584 that I have in my Shoei RJ Platinum helmet? I don't really care if the microphone sounds better, just would like better sound with some bass.

 

I thought for a second you had something useful to add... We want to cut the cord here, not but a new one!

 

Well its been a couple days with no reply. So I guess there isn't much difference.

 

So lets see if I can net this out .......... there is no HD, vendor, or 'home-grown' product to provide full BT connectivity yet, right ? (For now, I'm keeping the AKE product out of this assessment)

 

I'm sorry, I've read the entire thread and I'm a bit confused. An SMH10 is a headset mounted to the helmet with the microphone and speakers. An SM10 is a BT transmitter that has an adapter cable plugged into the 7 pin HD connecter. It seems to me you said a few times that the SMH10 was the transmitter. If I don't care much for the CB (though I do have it) an just want to hear HD's radio in my helmet and maybe answer the rare phone call I may receive while riding can I use the SM10 transmitter with my existing SHM5 headset? I assume my phone would be paired with the HD and my SHM5 would be paired with the SM10.
