Yellow is your constant +12 volt wire, and red is your switched +12 volt wire. It sounds like either your Red or Yellow wire isn't supplying the +12 volts it needs to. Only one of the wires is supplying voltage. You will need a multi-meter to check the voltage coming out of the Red and Ground, and the Yellow and Ground. The Yellow wire should have +12 volts at all times, even without the key. The Red wire should only have +12 volts with the key in the cylinder, and pointed to On. Find the wire that isn't supplying 12 volts, determine if it is switched, or constant, and then find a 12 volt wire that is switched or constant, depending on your findings.

My naxa nca-675 was working fine for about 2 weeks and then all of a sudden I notice the "Welcome" would flash and no buttons will work. Has the radio some kind of way locked? There shouldn't be...

I would recommend disconnecting your battery and see if that helps. As far as the owner's manual, it is worthless by far. It does recommend however, to press the reset button but does not clearly specify how to accomplish that.

Naxa NX-984 red microphone does not work. How

If you got it recently, you can check to see if the store offers any kind of return policy. If it does not, or enough time has passed that you don't qualify for it, you can also try Naxa's 90 day manufacturer's warranty. Check the support page here for the specifics of the warranty and the contact info.

I just installed my Naxa NX-670, and now when I attach the faceplate, nothing works.

If you run into this problem, be sure that all the fuses to the wiring leading from the battery to the radio are good, then be sure that the yellow wire is attached to the constant power source and the red wire is attached to the acc/ignition power source.
