new too all of this, was looking @ j&m radios. this is a c.b., radio & optional intercom??? also how does the speakers in your helment work?, is there special helmets you have to buy or can you modify the one you have, hopefully you can modify because i just spent some change on a full face shoei

We run JM2003 CB units on the ST and the 919. No problems and I wouldn't be without them. Best prices and info@:

If you need the intercom, then you need a dual unit.

Assume you're looking at the J&M handlebar mounted CB? To clarify your question, it's a cb radio that you can plug an outside music source into (it doesn't contain an internal am/fm radio). It comes in a solo version, or a version with a built in intercom for conversing with your passenger.
Headsets (microphone and speakers) are relatively easy to install in virtually any helmet.

Yes, I've installed headsets in open face, flip face and full face. I usually use the mic on the 'beam' for the open face and flip face and the mic pad for the closed face. The only thing I ran into on my HJC CL-MAX was I had to carve out a little of the foam to put the earphones where I wanted them. Basically, earphones go in the 'ear pockets' of the helmet, the microphone goes at the mouth, headset cord runs to J&M unit, usually attached on the left handlebar with the same bolts that hold the clutch master cylinder in place. Autocom (it usually is tucked in the tailpiece) allows you to interface whatever radio communication you want, J&M is basically a CB only (IIRC). Both are usually set up for intercomm with a pillion (which requires a headset for them also and a headset cord. Hope that helps some. The folks at Sierra are really great to work with and a great source of information. I have found that the FRS/GMRS radios have a greater range and less fussing with antennas than the CB units (I have both), so it depends on who you are riding with a lot what they have. CBs do have the advantage/disadvantage of listening to truckers on the slab who know where the police/accidents/traffic problems are. Hope that gives you some ideas.

I have the J&M CB radio interfaced to an Autocom unit. As the unit comes it has a CB radio, built in Weather Radio receiver, will allow an additional audio source (says stereo but have not checked) and an intercom. All of these things connect to the unit via a single nine pin connector to the unit (except the CB antenna which is another cable with a standard PL-259 connector attached.
The interface to the helmet speaker and mic require cables from J&M. To my knowledge there are no other standardized interface cables available so if you don?t want to roll your own cables, you are going to have to use the J&M cables and J&M mic and speakers. It all gets sort of expensive but that?s the problem with niche gear like this.
I have not used the J&M speakers and mics so I cannot comment on them. I have used the Autocom equipment which is similar. The Autocom mics work best when they are right next to the lips. The in the helmet speakers work best when they are next to the ears which requires some spacers in the helmet between the speakers and the helmet proper. It takes some work to get them lined up right but once you do the sound is much better. I have installed them in a full face helmet and the only issue I had was in trying to get the speakers next to the ears, they sometimes protrude into the head volume area of the helmet. This caused some interference with the top of the ears when putting the helmet on.
This can be overcome when donning the helmet, by pulling it out as you put it on. I did not have real success in making that work but there must a way since the system is used by lots folks.
The only drawback to using the speakers in the helmet is that you will have to put up with normal wind noise. This requires that the volume be increased to overcome the noise. While I have used the speakers in the helmet in both full and ? helmets, I personally prefer to use in the ear speakers similar to those with the iPod like devices.
There are several ways of doing this and I have tired most of them. My recommendation to you is that if you want good clear audio, you go with some type of sound isolation in the ear speaker system.
One that is available for a modest price is available from EAR INC. If you would like to know more about it you can PM me. In essence it?s a semi sound isolation system with good fidelity and noise reduction. It can be supplemented with custom molded ear plugs that increase the overall noise isolation. I have used both systems and I have found nothing else that compares to them.

EDSETS also makes headsets that work with the J&M stuff (and I like their quality a lot better). I find the EDSETS speakers to sound better to my tin ear than the Autocom ones. YEMV. Never heard of hooking up a J&M to Autocom. Very interesting! The headset cord pinout is similiar but with a few wires switched around from what I can tell (this is on the old 5 pin setups).

The great affair is to move
I just purchased the J&M Integratr unit which is a portable-CD player sized unit you can put in your tank bag. (I bought the whole she-bang including helmet off ebay). I have the elite headset in a flip-front Nolan. Boyfriend has the same unit, also in a flip-front Nolan.
I took the liner and cheek pads out of the helmet to wash them (slightly used) and found that the speakers and mic were very easy to remove. The wiring just slips behind the liner padding. While mine has a boom, and it mounts to the Nolan specifically, you would use a mic pad instead since yours is a full-face.
It took me quite some time to decide on what system to purchase. I decided on the Intergratr as I can use either FRS or CB with it, and it has alot of options for hooking up other devices such as the sound from your GPS, Ipod or other music source, and it has a built-in FM radio. The only downside is the unit is big... as I said, about the size of a portable CD player. It seems whichever system you purchase you are going to hit at least the $300 range.

I have the pin out if you are ever interested and it's posted here in one of the forums. It works, although there are some challenges in connecting the mic side up to the J&M, audio overload or just RF in the audio. I added a simple filter that seems to work. Audio reports on the CB are good.

Right now I have one of ST1100s set up with the old Hondaline Valk system (similiar to the J&M) and an Autocom Pro M1. I just swap my mp3 player and radar detector connections to which ever system I'm using and swap helmets. What I would love to get to is one headset (the EDSET one), one push to talk (I have the Autocom one and the Valk one), and one cord connection. The Valk system has the integrated CB, intercomm and aux feed and works really well, but it is a pretty 'closed' system as far as I can tell. In the perfect world, I would figure out a way to integrate a FRS/GMRS with the Valk system but it's far beyond by soldering/electronic abilities!
should mention that sierra-mc or edsets either one will, for a fee that is worth it in my opinion although sierra is much less, will install the headsets into the helmet you send them. check in advance to make sure it is a helmet they will do the install on. basically, sierra will install a j&m headset for you and edsets will install their edsets. i think sierra did an install for me on a shoei rf-1000 for 25 bucks. i wear earplugs and cannot discern any difference between the two sets. i am convinced that edsets quality is a notch higher than j&m though.
+1 on Edsets being better, but I would go more than a notch better. I won't buy anymore J&M headsets as long as the Edsets are available, unless an even better headset becomes available.
I think I have entered the twilight zone!!!! not real tech savy but learning, what is frs &gmrs i'am guessing the frs is some way to talk but isn't c.b.--not sure about gmrs, what i think i want is a c.b. & some way to listien too music can you hook up a mp3 player too this THANKS stuff???:bow1::bow1:::bow1:
Oh my friend you have indeed entered the zone of no return! Hold on to your wallet and get ready for a ride.
CB is great for the highway to reach others or monitor truckers. Or if you ride with others that have cb. Gmrs, frs offer much better com and are great if you ride with others that have the same type of radio.
If cb is your choice then the j&m unit is simple and easy to use. Offers input for your mp3 or other audio source. The dual unit has intercom function.
The only weakness that I can see is the expense of adding multiple inputs, gmrs, phone, gps,xm ect. That can be done but is expensive. Also J&M uses a open mic system so if you have a passenger there will always be wind noise.
The others are Starcom1 or autocom. I have used both and prefer the autocom. Both offer multiple inputs and vox activation of mic. I just think the autocom does it better.
The autocom and starcom1 are hubs and do not have radios. For this system you can add your own inputs many at the same time and the units will give priority to you inputs.
I have gone insane and have autocom super pro avi, zumo gps, zumo xm radio. mp3 player in zumo, gmrs radio with external antenna , bluetooth from zumo to phone,bluetooth to autocom unit,J&m cb unit run thru autocom. Autocom mics with j&m speakers, and option of bigear.inc molded in ear monitors. Thinking of external speakers also. This all works great thru the autocom hub.
I did all this thru bits a pieces, but it is an addiction , be careful! One thing nice about quality systems is that if you get tired of the whole thing they are easy to sell and get great return on your cash.
