OK...My bike is 04..Radio is 02 cassette..Everything works GREAT at idle..But volume gets so loud when riding i have to turn down then when i stop i have to turn up to hear and so on!! I have adjusted avc acording to directions(DAWG..THANKS!!!)..Original at 2 then i set at 1 better than 0 (AVC should be off at 0) but still getting(LOUD) volume raise at speeds..Was told i can disconect (green/white) wire in back of radio to disable AVC...ANYONE know if this is TRUE or any other Info/impute would be very much appriaciated!!!!! Thanks for your time and help its driving me crazzzzzy[:@]....Thanks R.W.

 

I don't think I've ever met anybody whose radio was too loud at speed then too quiet at idle. Mine's just the opposite.

 

BG.....First time for everything!!!!!...Thanks for impute!!!! R.W.

 

do you have a wireing diagram that may help i can look at mine tonight to see what wire could shut the AVC off

 

I curious, if setting the AVC to 0 shuts it off, why clip a wire?

 

Jimbo.Even with radio avc on 0 (should be off) it is still working..Must be radio not receiving signal right?...Just thought i would disconnect avc and just manuel adjust it. I think its radio problem but at this point dont want to sink any more $$$ into it.Thanks R.W.

 

R.W.--the AVC gets its signal from the white/green stripe wire--it's probably in chamber 9 of your Base Audio Connector. (If I PM'ed you and referred to it as green/white, my bad--the speed signal wire is white with green stripe in chamber 9 according to my '04 HD Service Manual wiring diagram.)

Whether disconnecting this wire will take the radio out of AVC (so you don't have the volume changing) I don't know--removing the wire will prevent the bike's speed signal from getting to the radio, however.

Give Radio Sound a call; they're HD's supplier of the radio you have, and they are good about providing customer service. Here's their number: 502 267-6768.

 

Harleypingman....

Once again Thanks for your impute, i will call Radio Sound and see if they can give me further updates!!!! R.W.

 

Harleypingman has it right,
According to my 02 service manualthe speed signal from the speedo to the radio is a White with Green Stripe wire. It is located in the back of the radio at pin 9 in connector 27. This is the connector on the lower left of the radio when looking directly at the back. Hope this helps.
