It is due to the bad connection to the battery or your battery can be weak and also check all the connections sometimes loose connections can cause sound, a weird sound.

SOURCE: everytime i turn my car

Most stereos have two power connections. One is "constant" (aka always connected to +12V) and the other is switched on/off by the ignition. They may go be various names. The idea is that the constant +12V keeps the stereo from losing all of the settings while the switched power turns the stereo off when the key is not on "start" or "accessory". It sounds like the both connections may be made to the switched power on your car, causing it to go completely powerless when your car is off.

Are the presets reset after you turn the car off or only after you turn your car back on? If they only reset after turning the car back on, it's possible the battery and/or electrical system is having trouble keeping the system voltage up while the starter is trying to turn the engine.

The illumination signal is usually used to let the stereo know when you've turned your headlights on, so it can dim the display automatically. Should be completely separate from your issue.

SOURCE: JVC KD-NX5000 NOT WORKING PROPERLY

I had the same problem, where the Sat radio, the bluetooth and the ipod were all non-functional. Turns out, they all go through one central hook-up, so you have to make sure that connection is good.

When mine did not show up or function, I looked at the install under the foot board of the front passenger seat that the installer did, and nothing looked out of whack. Upon closer inspection, one of the cables was had been pressed out of it's proper place and loosened enough to cause a bad connection.

I don't care for the install, but there was no problem with the equipment, so check all of your connections. Even to the point of pulling them out and reconnecting them to see if that fixes the problem.

Connect Yellow to Battery (always 12V), red to ignition, and black to ground. Disconnect all others. Check it. If the radio stays on and plays CD, then radio is good. You may check other wiring

Can i play music through my iphone4 into the front usb on my jvc kd g646?


yes, this is a data port. Use your iphone to USB cable. Not sure it will recognize the apple audio format, but you can convert your songs to mp3 for playback if it can't play the ipod files. Please let me know if you have more questions, and thanks for using FixYa.

My jvc kd-g820 will not produce any sound and not accept cd


try to find the reset a little indent on the face or hole when you remove the face and push in for 2 to 3 secs with a pen or paper clip. Then try your cd again. Still dont work check to see if you have another cd jammed inside and your trying to put two cds at once.

Ok for your no sound problem. a bad speaker, short speaker (one 1 speaker shorts out all will not work cause the radio is in a protective mode), factory amp needs to be turned on, bose system or amplified system in car needs to be rewired to bypass factory amp), buy special car harness to make factory amp compatible with aftermarket radio, late ford models the back speakers are crisscrossed.

Next time please give car info and type of system you got in it so I could narrow down the possible problems a little bit easier.

Jvc kd-s590, installing in other car and only the att (red) light comes on no display or sound. tried resetting, fuse is good. that's it.


sounds like only the constant(yellow) wire has power. you need to make sure that the switched wire(red) has power as well. good way to trouble shoot, is to hook the red to the yellow to see if it powers up then, if so you know the radio is ok, you just need to find a better power source for the red wire. hope this helps.

Power will not stay on


Sounds like you're not getting voltage on the accessory power lead. This is the red wire at the back of the deck, and it supplies power whenever the key is switched on. It's possible that your vehicle's radio fuse is blown.
