BMW JMCB 2003B System

Before I email J&M, I thought I would throw this out. My 2008 RT has the BMW JMCB 2003B system installed, BMW Navigator (Streetpilot III), and XM radio. The GPS was connected by a 3-prone plug (power, ground, sound)? I disconnected the plug when I installed my 2610. I notice that coming off of the bikes CD unit is a male plug which plugs into a coupler then another male plug. I assume that this feeds the J&M system? My other questions are:

-- Is there a way to connect a HF-820 Bluetooth device to use with my cell phone? The HF-820 worked on my LT with a Autocom system. If so, where would you connect it to?

--There is a huge volume difference between playing the bikes radio and switching to the XM radio. I can turn the auxiliary volume knob on the CB to make the xm louder but it is still well below the radios volume. You have to be careful when switching from the xm to the radio. Does this seem normal?

--I do not know if this is the bmw side or the JMCB side. Every time I start the bike (with xm as the default), I have to manually increase the volume. Is this normal? I have not tried it with the radio. (My LT use to retain the current sound when I turned off the bike.) On this RT, it took me a little time to figure out how to make the adjustment so that the sound does not blast you while moving and become silent when coming to a stop. I have it set to "4".

--How do you think the xm radio is connected to the JMCB system? The xm has a male (2.5 or 3.5) male plug. Again, this relates to my first question. If I figure this one out, maybe I can connect a "Y" adapter, but by doing it this way, I do not think the HF-820 will silence the radio when it rings.

Thanks everyone!

Re: BMW JMCB 2003B System

I know that it has been over a year since my last posting on this subject, but has anyone connected their cell phone to the JMCB 2003 system? I just emailed John yesterday and am waiting for a reply. I am still looking at connecting my HF-820 blue tooth device to the JMCB. I see that there are two 3-pin black plugs. I do not know if I can use that or if their system does NOT support cell phones.
My xm radio is playing through the BMW's radio aux 3 output, so it does not link to the JMCB system. It still plays through the helmet speakers.
As for the low volume with the radio each time I start the bike, I connected a boosteroo (?) device to boost the output. I no longer have to adjust the volume of the radio.
I tried connecting the bluetooth device to the radios aux 3 plug (the same as my xm radio). I can hear the phone ring and the other person talking, but I cannot talk back (again because the output is going through the radio and not the JMCB).
The next step may be to ask John how much it will cost to upgrade. I jus do not believe the JMCB system may not offer cell phone support. I had a ten year old autocom suytem on my LT which supported a slew of devices.
Any help is appreciated!

Mike,

I just did the economy install of a J&M Integratr IV into my 2008 RT. It has very similar functions as both the 2003CB and the factory BMW LT Comm System.

I used the optional cord to connect the Zumo 660 to the cell input of the Integratr. This allows you to bluetooth a cell to the garmin, then pass through to the headset.

I hard wired the Integratr to a switched circuit through an Eastern Beaver 3CS with relay and put the unit in the glove box.

I spent about $165 for all the parts and now have FM Stereo, Intercom, GPS, MP3, and cell functions....my RT did not have the BMW radio.

You can also hook a CB through it and radar detector..

Re: BMW JMCB 2003B System

Thanks for your reply Ron. Sunday night at 11:00 I received the following email from John Lazzeroni:

Michael ,,,,,,,,

We will be releasing a new Bluetooth cell phone integration kit for the JMCB-2003 within a month or so ,,,,,,,

That is what I would recommend for your set-up ,,,,,,,

Re: BMW JMCB 2003B System

With thinking of this some more, I emailed the following to John Lazzeroni at J&M last week:

Hi John, Another question regarding connecting my cell phone to the JMCB-2003B system. Is it possible to fabricate an adapter that goes from the passenger connector (cord) to a 2.5mm female headset jack? I can plug this adapter into my Bluetooth HF-820 device. When I am riding by myself and receive a call on my cell phone I can always mute the audio system and receive the call. I just cannot see paying $500+ for the CFBR unit since I do not ride that often.

If this is a possibility, I may also ask you if it would be possible to also fabricate a Y adapter for when my wife is riding with me.

I received the following from him:
"I don't believe that will work very well ,,,,,,, but certainly something to think about ,,,,,,,,,,,,,,,,,,,,"


I will give him a couple of weeks to think about it and I will ask the question again. I would think that this would work. Anyone with thoughts about this?
