2006 ultra radio has no sound

Radio has power but no sound, can't be controlled by handlebar switches or radio buttons. Was riding one day, volume went to full, pulled bike over, shut bike off, turned back on, and that's where I'm at today. I have a radio that lights up with no sound or control.

    It was sold to me by Hogties. Brain of Hogties sold me junk and rusted parts and did not send all the parts I payed for, so beware of this swindler

My radio will not accept any input from the handlebar mounted switches......not on the volume treble or bass or the other side with band. In addition i cannot turn off the unit, it will not accept any...

If there is no audio, the radio is locked on an fm station with preset 1 highlighted, and no control from the handlebar or face, the TMS 320 processor is locked. The radio cannot be repaired. try to get your HD dealer to exchange it.

On an Ultra Classic Harley's handlebar volume control "how do you install the knob?". Is there a special tool or method to hold the spring loaded shaft while the knob is pressed into place?

Are you putting on a chrome button or just reinstalling the original? Either way, I seem to remember that it is just pressed on, no special tool or method. If you want, you could always open the housing and see if you can hold the inside piece with needle-nose to keep from damaging anything.

Volume can not be increased low static sound

No / intermittent audio is caused by vibration damage to the audio circuit. Unit needs to be put under a microscope and inspected for micro cracks in the solder joints of the audio circuit components.

Volume control is adjusted by remote switch on handle bar. You can contact HD for a wiring harness schematic
