radio problems

Postby re774c » Thu May 01, 2014 6:28 pm



So,I have a 1989 GL 1500 with four speakers and the fader control. My question is what controls the radio volume to increase with speed. Mine has a short or something it increases and decreases with out any reason, I just don't know where to start looking.

On the radio there should be a knob labeled 'AVC' and that controls the automatic volume as the bike increases and decreases speed.
I had the one on my trike with the dot at the top towards the handlebars. Find a happy medium with that knob for the right setting.

Take a look at the MUTE setting. I suspect that is your problem. I normally leave it at minimum and the AVC at maximum.

The MUTE is there to decrease the volume of radio audio when the microphone senses intercom audio. Unfortunately, wind noise is also intercom audio and it will decrease your radio audio too. I just turn it down and don't worry about it.

The AVC on the other hand will increase the radio volume when your speed increases above approximately 47 mph. I do not know how many db it increases by but it is a set amount and does not increase as you go faster. Then going down through about 42 mph, the audio will decrease.
