No volume is coming through the speakers ;but the volume bar increases and decreases

does the buzz increase and decrease with engine RPM? if so a capacitor/filter is needed in the powering of that circuit (although that should not happen with a factory unit if installed as spec'd by the manufacturer).

try to remove the unit and open it and clean the knob from inside with non lubricant cleaner while you turn knob right and lift
if the problem still presents change the knob with the same one

Fault is in radio.

Not sure about your car, but they come equipped now with a program that will decrease the sound level due to the traffic around and increase the volume to compensate for road noise. The best thing is to look in your manual, under the radio section and see if there is a section for this issue. If so, it can be disabled. We have a car that does it and I flipped out when it started so I disabled it. Not alot of help but it will give you a little insight to a possible solution.

Hello you must have your speakers disconected or perhaps the speakers are not in the car my solution is chek and make sure all the speakers are in the locations where they should be.Some times people remove those when they sell the car

dear it is fault with music system ,you have to replace stereo.

You may have a bad connectors to the Throttle position sensor. A TPS is actually a varistor, or same thing as a variable resistor. It is like the volume control on old stereos that do not have digital volume control. The computer determine throttle angle by input current which varies with the resistance. Make sure the connectors are good before you change it otherwise a new one will not solve the problem. I know how to check a TPS, but it is hard to explain how to do it, but I will try anyways. The TPS has 3 terminals. The resistance should vary as you turn the TPS. In respect to the middle terminal one side will increase, and the other side will decrease in resistance value. Sometimes it is not the center terminal that is the common point. so either way out of three you one that is common to both which should vary in resistanced in oposite ways, one side decreases, and the other increases as it is turned. A short course in electronics. As elctricity flows trough a resistance its current decrease as the resistance increase. The resistance value on a TPS should be around a few thousand OHMS, and the lowest value is around 500 OHMS.

8. Clock: Press and hold CLK button until the
hour digit flashes. Turn the volume
control to increase/decrease the
hours. Press again to set the minutes. Turn the volume control to
increase/decrease the minutes

On some wiring systems you have to make sure the wires are not touching neg. and pos.just try some speakers without actually installing them. make sure mute button is not on.
