JVC Car Audio & Video - Recent Questions, Troubleshooting & Support


Not sure if this will help any other owners since my answer is 4 years late, but this is what I found from another user. Apparently if you mess with the wiring too often, it goes in a safe mode which you need to do some button trickery to unlock the device from it's safe mode. These are the Steps.
1.Disconnect power supply
2.Press [MENU] and [UP arrow] buttons and keep holding.
3. While holding the buttons [MENU] / [UP arrow], connect the power plug again
A. The display will show "DC ERR"
*** if it still shows "Chk wiring ..." repeat the steps above until you get "DC ERR."
4. Press [UP arrow]; the display shows "DC1 ERR"
a. Press and hold [UP arrow] and it will show "DC1 OK"
5. Press [Down arrow], the screen will show "DC2"
a. Press and hold [DOWN arrow] and the display will show "DC2 0"
6. Disconnect the power from the back of the unit.
7. Remove the Face Unit.
8. Reconnect the power from the back.
9. Use a sharp object and press the [RESET] hole for 3 seconds and release.
10. Reinstall the face unit and turn on the power.

It can be due to the lens of the player, or it can't take the command properly.

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.

Hi, there is no exact settings for your sound sysytem. There could be many reasons for the distortion on the front door speakers.
best to find an certified car sound installer who will check your installation quality, and tune up the entire system according to your music selection style.
Cheers.

The remote wire is usually blue. Make sure u do not use the blue for speakers. The remote wire should be in with the power wires.

Most car harnesses will correspond by Colour thus look out for an orange Colour from the pre-installed/ pre-selected wires.
Now the issue is, not all cars come with such wires pre-selected and installed ie bunched up with the Audio cluster, for such, you need to identify the wire yourself that connects to the light switch on your dash board and tap into it.

the accessory wire needs to work with the key turning. the battery wire connects to the battery. if you have a volt meter it can be very easy to find your wire connections in the fuse box. find the ignition fuse in the box set your meter to volts dc take your black lead to a chassis ground and the red lead to one side of the ignition fuse turn your key to accessory and see if you get 14 volts if you do get it thats your connection. if not try the other side of the fuse.

Press the "Hour" button (or right arrow button) to set the first and second digits of the code. Release the button once the four-digit code is accurately displayed. Press the "Mode" button to lock in the code you set. Turn the stereo deck on by pressing the "Source" or "Power" button to complete the reset.
