Project completed / At least for me. And it works!!!
I did not hear back from any vendors with a positive response concerning the Valkyrie Interstate, except for AKE. Link is below:
http://shop.ake-electronic.com/index.php?route=product/category&path=79_84I can not confirm that it will work with the Valkyrie, but I did receive an email that they did have a product that would. Let me state, if it plugs into the regular headset connector, it will work.
The problem with the Sierra connectors are that they install inline with the headset harness. Apparently our harness is different than a Goldwing 1500 or 1800. I could not confirm that. They did not respond to email requests.
What I did.....
I built an adapter. I am using Sena SMH10 headsets. My wife and I can communicate person to person. She can connect to her phone. I can connect to mine.
I used a SMH10 on the bike. I built an adapter using an old headset plug that interfaces with the Valkyrie and used a Sena helmet clamp kit for the basis of on board bike system.
Someone had already done this, and I can not take credit. He is the designer of the Sierra interface that works with the Sena systems.
His system uses a smh10 and a sm10. You switch back and forth to get stereo in your headsets, and then go to the mono system for CB usage (transmit). You can listen to the radio, it is just in mono in that mode.
I don't like headsets blaring in my hears for hours, so I just used the mono system (SMH10 and did not add the SM10 for stereo) and I can talk on my CB, or even listen in my headphones, but I usually just leave it on the bike speakers.
How it works. I leave my headset in standby or connected to my wife's headset if we are talking. The phone will override if it rings or you make a call, it does this by default, automatically.
If I want to talk on the CB, I connect to the bike unit, PTT on the bike works as normal, and you can choose to hear the cb or radio or both using your on board bike controls.. (just like a wired headset). But, it is in mono, not stereo. Phone still overrides if it rings or you make a call.
Disconnect or un-sync to return to standby, or reconnect to your riding partner or whatever device.
Transmit audio was really decent on my test CB I had set up.
Links for the interface design, and the thread that I found my information on are below.
http://support.sena.com/entries/20845262-would-love-to-see-a-goldwing-factory-audio-cb-interfaceIt took me about an hour to solder the resistors and plugs together. I am working on mounting options and will decide if I will need to charge the SMH10 while driving or not. I figure that is the easy stuff.
No more cables for me... Note: It is easy and cheap to just hear the CB and on board radio... This interface lets you talk on the CB also. That was my long term goal for this project.
I have several dollars invested. 3 SMH10s One for me, one for the bike, one for my wife. I used an extra SMH helmet clamp kit as the mounting option for the bike because I can plug and unplug my headset cable interface from it. I spent a few buck in plugs, resistors, heat shrink etc...
Good luck with your quest if you seek to do as I have done. It is a shame that no one has come up with an off the shelf unit that is simple and cost effective. If you read the thread at SENA, it has been on going for years..
I didn't post pictures, since it is only a cable, and it looks like the ones in the link above!
Ride on...
