jakestercp10 I bought the axxess aswc-1, do I have to do the resistor set with this, or can I use the wire from pin #7? Unfortunately I'm not the guy to do soldering, but I was looking at a couple set ups that they showed on their website for BMW cars, and it says use pin #7 and your done. Any idea if it works, if not I'll find someone to do the solder for me.

I was wondering if you buy an adapter plug, is it plug and go? Or do I have to figure out where the wires go? It looks like the speaker, ground and the constant on all line up, not sure where the on goes. Does anyone have a pin diagram showing what all the pins are? I have a 2000 k1200lt.

Thank you very much for answering my question. Yes, the 05 computer display is mounted in the bottom center of the instrument panel. Thanks again.

2003 K1200LTC
Most of the time I just use my iphone/bluetooth, thru the helmet..
Spotify, amazon music, pandora, etc.

I used this thread to help hook up a Pioneer 3500 a while back.
It worked well and all.

But i really missed the speed sensitive volume control.
Stop sign to 65mph, without changing volume.
Also, your not that guy at the stop light with music blaring.

Works so well for those summer days when out for a ride around town w/o helmet.

Searched and found an OEM radio to replace my faulty one.

JVC===am doing a combination of you and NoahAngel's radio install; followed your lead and purchased the JVC unit; Radio only has one "steering wheel remote control cable"; Ax.. adapter has the brown/brownwhite;

Where goes where?

Hello Noah; I have a 2002 K1200LT and only RDS works (all four speakers; mute/volume adjusts work just no radio; LCD display barely seeable as well. Ordered the wiring harness/JVC receiver/AWCS1 controller last night; printed off most of your information.

So here is where you can influence your druthers on me..lol; I like the idea of using the legacy pushbuttons; my LT has the side case mounted CD changer; will have to see if it works tomorrow but if it does, then would like to keep it and have it work via cd button on the display..

So look at what you have done and let my bike be your guinea pig.....
Once I hear from you, I will go find the resistors/breadboard etc..

How are you water proofing the circuit board if at all?

I have been in "One" rain storm that was wet enough to knock out my comm system. It only happened once about 8 years ago but it does mean that it could happen again.

Re: 2004 K1200LT Stereo Replacement With handlebar controls intact

OK guys, I've had my bike apart for 5 weeks now working on this stupid radio thing. I have picked Rays brain enough. So it was time I hopefully get to offer someone else some help. I went on Amazon the other day and ordered 3 wiring harnesses for BMW radios for about $6-$8 a piece. The first one arrived this afternoon. This one will work just fine for the radio wiring harness. I had to modify it slightly. I pulled the blue wire through and the orange wire through. I placed them in the 2 holes where I needed a pin to go into the connections. I then placed black silicone in the holes, to reinforce each wire.
The brand of wiring harness is SCOSCHE Model BW01B. Here's the link: scroll down and "buy both" to get the antenna modifier with it.

armichels Thank you all for all this fantastic information. Picked up a 2000 LT on Saturday (first bike). Tore it down yesterday, followed these instructions... Everything worked perfectly. Installed some Pioneer Speakers in the front, a JVC head unit with Bluetooth, and USB for charging. Got all the adaptors for a 2000 3-Series, including the handlebar wiring. It's a great bike, looking forward to a ride next weekend.

Not on mine. I removed the intercom and put it on eBay as I have not use for it. Electrically speaking, the stock intercom on the LTC is powered by the stock head unit amplifier. Removing the stock head unit will defeat the intercom system.

Re: 2004 K1200LT Stereo Replacement With handlebar controls intact

I was asked to clarify the resistor portion of the installation.

As explained by noahangel11, the ASWC and ASWC-1 interfaces require a small modification to properly interpret the handlebars switches.
They original function is to short to ground and let the LCD unit do the rest. To work with the ASWC, they need to do more than that.
So we are installing individual resistors on each wire with a value from 1 to 5K OHM. This is a great and easy way to creating unique instructions to be delivered to the interface. That is really all.

I am attaching a simple schematic and a BOM to cover how I implemented my radio and interface on the bike.

All I did was creating a breakout board. I installed it between my handlebar switches (LCD connector) and my ASWC-1.
To one side of the board I solder all the ASWC-1 wires and to the other I solder the wires coming from the LCD connector (handlebars switches).

Note that my LCD unit is no longer connected to anything as I am not using the original push buttons (over the tank).

I hope it help.

Re: 2004 K1200LT Stereo Replacement With handlebar controls intact

I finished my installation just few weeks ago.
I do not miss the original setup because with the handlebar controls working well, it is like nothing has changed for me.

Updating to the JVC head unit with a front USB port, allows my iPhone to charge while playing Pandora so life is good!

I am very happy with it, here are some more pictures after removing the intercom and with the top cover installed. You cannot really tell anything has changed.

Re: 2004 K1200LT Stereo Replacement With handlebar controls intact

In my case you are correct, the LCD has no function whatsoever.
I recently saw a picture of an LT with a radio head unit without LCD. I am not sure what there is but I am looking to find something like that.
In alternative bondo should do it too.

Hi there,

I never heard about such interface but I just finished my instal using an ASWC-1 and a small board for the resistors. In essence you can use any resistor from 1K Ohm to 5 K Ohm. I used what I had in the shop (1 - 1,5 - 2 - 2,5 - 3 K Ohm) and got both front and rear handlebars controls to work as good as the stock. The front/rear wires are in parallel so you only need one resistor per wire...

Let me know if you need more details or any help.

Your project inspired me and even thought I recently repaired my stock radio, not having USB, Bluetooth and iPhone support I decided to go with something more contemporary. So after 2 days of intense thinking, tonight I completed a similar instal on my 2000 K1200LTC.

I used the newer ASWC-1 interface and a supported JVC media player (KD-X320BTS). This player does not have a CD player but has a front USB port and Bluetooth, that all I needed.

I found the ASWC-1 at the local Best Buy for $89 but with their "Price Match" I was able to show them Amazon selling it for $43, so I got it for $43 at Best Buy

I used a small board to which I soldered 5 resistors (500 Ohm increments) for my 5 handlebar switches. It is a breakout board between the interface and the handlebars switches. The interface works extremely well and only took me few minutes to custom program it. I was able to fit everything into the original radio bay where the media player small profile helped a lot!

NOTE
There is a wiring difference between the ASWC and the ASWC-1: The wire in PIN4 is Green/Yellow as opposed to Green/Orange. The rest is identical as per your schematic.

Thanks again for sharing this awesome project in great details.

Re: 2004 K1200LT Stereo Replacement With handlebar controls intact

I had read your post & others on this subject & it's always nice when I can make use of someone else's hard work. When I bought a used 96 RT this winter with a bad radio I decided to experiment as well. I wondered why the connection for the "wired remote" needed an interface device like the Axxess AWSC Steering Wheel Converter. Does it convert resistance values to some sort of a data stream that the radio needs or is the radio connection just looking for resistive values as well. As it turns out with the radio that I used, different resistance values across the tip & sleeve connection of the miniature stereo plug connector performed the different functions. My bike only had 4 buttons on the handlebar controls so I quit looking for resistance values for other functions when I found the four I needed. I found 2 others while searching for the 4, but it was a PITA trying individual resisters. A wide range variable & maybe a decade box would make finding the other values a lot easier. The radio I used is a Pioneer MVH-X370BT. It is an AM/FM, bluetooth, USB, Aux input radio. No CD. If I ever have to replace the radio on my LT, I will probably dope out other resistive values to make use of the other buttons that will be available.

I beg to differ, Raymond not only has the ambition but more importantly is one smart electronics guy to figure all this out. You might as well discuss the workings of the space shuttle because I do not understand one thing Raymond is talking about.

Glad to have Raymond on board we need another guru for our fold, great job Raymond.

I had to guess and try different wires on different resistors as the manuf. didn't want to divulge the exact wires ranges. There is no reason why you can't solder directly to the LCD switches. I did it my way to reuse the connector so I could unplug it.
Thanks, that helps.
Should be able to go back to the shack & get what I need now.

Going to try and go beyond the volume + and - and mute on the handle bar like you did.
The radio has the USB and is compatible with iPhone's / iPods so I'm going to try and use the LCD panel also.

Really appreciate your help.
