JVC KD-G340 Power Problem

I just bought a new JVC receiver for my truck to replace the factory one that had stopped working.

When I hook up the yellow wire (unit is grounded, red wires connected), the unit will start up, buzz a second or two (::think CD ejecting sound::), then go off. Pushing the I/O doesn't do anything, but if I hit the eject button, the unit will try to eject, then go back off.

Any ideas? Am fixinng the cd player in a '99 Ford Taurus. I believe the problem is in the wiring. Cd player will not turn on. Will turn on momentarily upon hitting the "Eject" button. One problem that i see is that whomever originally wired the cd player in the vehicle did something wrong. To the right of the CD player is a button controlling the Rear Defrost. If that button is on, the CD player will not function at all, including the minimal power it gets when presing the "Eject" button. I'm debating on whether I should disconnect the main power supplies for the CD player and rewire them to a different position (Different circuit).

Why does my jvc kd-r526 reset to factory default everytime i turn it off


Try connecting the yellow wire to a constant power source. That is, a source that still has power when the key is turned off. The yellow wire controls the memory of the radio.

Need to wire JVC model KD-G340 into a 97 Kia Sephia


Do not cut the wires from the car. Instead, call Crutchfield at 888-955-6000 and order the adapter part number 120701003. When you call them, ask for color coding. For JVC, refer to the attached picture. Match the adapter color code with that of JVC. If the adapter color code is the same, then connect ground (black), battery (yellow), and wire from ignition switch (red) securely. Turn on the car and see the radio works. If it works, connect one by one speakers and confirm. Remember, perfect connection gives reliable installation.

JVC KD-G340 Power Problem


I had this same problem...you probably have the wires wrong. Double check your connections for the red and yellow wires from the headunit. Make sure that your red wire is going to a 12 volt source that only switches on with the ignition.
