"The CD and radio aren't working but everything else is"? You'll have to elaborate on "everything else". What are you trying to do? If you're adding a CD changer that uses an FM modulator, that simply feeds in what looks like an FM station, so yes, the FM has to work on the radio.

Okay, so what I'm saying is the radio and CD player from the Honda stereo isn't working but the lights, the clock, the volume and all the other buttons work, its only the sound that doesn't. So what I'm asking is that can I buy an Fm transmitter instead of fixing the whole car stereo that will cost me 500$ to make the sound work or will it work? Or can I also buy a different small stereo that I can install separately and will the sound still work?

How can the volume work but the sound doesn't? They're the same thing. You see why I'm confused. What kind of FM transmitter are you referring to? The only thing I've ever heard of is an FM modulator that takes the audio from a CD changer or a satellite receiver and puts it onto an FM frequency that the radio can pick up just like any other radio station. The radio's FM and audio circuits have to be working for those modulators to work. To say that another way, you have to be able to pick up and listen to FM stations. To go even deeper, all FM circuits feed into the AM circuit in almost all radios, so, except for a few rare cases, if the FM works, the AM will too. You CAN have a dead FM system while the AM is still working.

It just occurred to me, do you have a volume level on the radio's display, and THAT'S what you mean is working? That would make sense. If that's what you're saying, it sounds like you simply have an issue of no sound. That can be caused by a loss of the 12 volt memory circuit. Loss of that circuit, due to a blown fuse, affects various radio models differently, but on almost all of them that will include, if the clock works, it will reset to 12:00 or 10:00 each time the ignition switch is turned on. If the clock is always at the correct time, that memory circuit should be okay. That circuit is usually tied in with some other system that is always live such as the horn, or more commonly, the interior lights, so you'll need to check for a blown fuse is one of those circuits is also dead.

You also have to consider whether the car has a factory-installed amplifier. If it does. Check for a blown fuse for that. A problem inside the radio can also cause it to fail to tell the amplifier to turn on.

Yeah you're right! The clock doesn't reset and does it mean I will have to open the car stereo and check for a blown fuse and if so what should I do?

There's no fuse that you're going to replace inside the radio. You might consider taking the radio out and having it tested at a larger salvage yard. That will tell you very quickly if it's a radio or wiring problem. You will likely need to know a code though for it to work. That was a problem with Hondas.

Most import radios have a 10 amp fuse on the back, but that's for the memory circuit, ... I think. I haven't worked on many of them because a lot of radios for Toyota and Honda, and some for Chryslers are built by Alpine, and Alpine will not allow the authorized repair centers to sell me service manuals for their products. I get even by not buying Alpine products.

Okay and one last question, if the wiring is the problem between the stereo and the speakers, can I buy a stereo and connect it to the speakers? Or the sound is just dead? Because all I want is to listen to music or the radio but I don't want to pay 500$ for a new car stereo, I'd rather get the cheap ones.

There's a number of variables, and it would be real helpful to know what's wrong first so we know what will work. Inexpensive radios generally don't use or need a separate amplifier so if your car already has one, it will have to be bypassed. If there's no amplifier, the speaker wires can just be cut from the original plugs and connected to the new radio.

It is possible for a speaker to fail completely, but never all four or six at the same time, so that is not the problem you're having now.

You also might consider looking for a used original radio from a salvage yard. That would be the easiest way to pop a new radio in with no wiring worries.
