Re: will not turn on

Maybe you lack ground connection, connect the antenna cable and connect the unit to the chassis of car.

also check the fuses on back of unit and fuse box.

I recently bought a JVC KD-R311 car stereo, its a great stereo but my settings dont save, for instance i set the perfect sound adjusting bass/treb/mid/loudness and whenever i turn my car back on after...

You need to have the yellow wire from the stereo connected to constant battery/12 volts. That wire supplies power for the memory, if it is connected to ignition power, when you turn off the car, the power for the memory is off also.

No power to stereo.

use wiring diagram back of stereo. check 12volts supply by multitester dc.

Stero not coming on

What kind of car do you have? This can make the difference. Many cars with small engines (eg. Geo Metro) simply do not generate enough power to operate the radio. Other times the car can generate enough power to support the radio, but when you plug something into the cigarette lighter/power outlet the radio shuts off because the car isn't powerful enough to handle both. The first thing you need to do is to make sure that the car's electrical output is sufficient to operate the radio, after that it would be a good idea to make sure that all of the wires are connected properly.

probably the mode you are in, there is a mode for auxillary amplifier that disables the internal pa, in the aux amp mode you won't hear anything.

Car stereo


Most current Pioneer car stereos needs two wires plus the ground wire to be activated. The yellow is connected to the always on B+12 such as the positive terminal of the battery, the red goes to a switched B+12 such as the ACC of the IGN switch while the black of course goes to the chassis/body ground.

Should the above been done correctly and problem persist, then perhaps the fuse may have blown, there is a loose connector at the rear of the head unit or a probable internal electronic defect has developed.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
