JVC KD-G421 - cannot access menu to add ext-in

The JVC KD-G421 only shows the option to change EXT IN from the CD changer to EXT IN when the current source is FM, AM or Disc . See the following page at ManualsLib: https://www.manualslib.com/manual/81662/Jvc-Kd-G421.html?page=15#manual . Assuming the J-Link cable that you added is the KS-U57 or KD-US58, the unit is still looking for (and not finding) the CD changer. Press the SRC button repeatedly until you get to FM or AM. (Disc will only show if there is a CD in the CD slot.) Then try pressing and holding Sel. Use the fast forward/up or fast reverse/down to get to EXT IN on the display. Then turn the tuning knob until EXT IN is selected. Press Sel again to save the setting. Now see if the EXT IN is listed when you press the SRC button. Page 13, https://www.manualslib.com/manual/81662/Jvc-Kd-G421.html?page=13#manual , shows the general procedure for setting the preferred setting mode. I hope this helps. Cindy Wells

How to resolve miswiring problem on jvc steeo car

MIS WIRING" is displayed when there is a DC offset voltage detected at the speaker terminals ('+' and '-').

This is normally caused by connecting a '+' or '-' speaker wire to either GND or Vcc (+12V)

1. Collect cable not being used and make sure they are tapped off and reset

2. Remove a connected cable one at a time and press RESET

3. If after a cable removal and reset the error goes away, last cable removed was fault. Examine cable for short.

4. If you remove and reset all cables except for (RED, YELLOW, and BLACK) and you stilll have error, the short is internal of unit and requires service

JVC KD-SX990 Stereo randomly off and on

If you've confirmed that it's actually losing power (a CD will start over when the display and sound come back) instead of just the display cutting out, then you should first check your fuse panel in the vehicle, and make sure the fuse that provides power to your radio is seated firmly and securely. Try jiggling it if you can and see if the radio cuts out then. If it seems fine, take the radio out of the dash but leave it connected. While it's powered on and playing, jiggle the connector that's plugged into the back of it. If it's still fine, do the same thing with the wiring harness that's connected to the factory wiring. At one of those connection points (fuse panel, connector at rear of radio, or connection to the factory wiring in dash) you may have a loose connection. If you cannot repeat the radio failure by doing this, you likely have an internal problem, such as a failing power supply, or it's overheating and shutting itself off. If you need further help, I’m available over the phone at https://www.6ya.com/expert/reginald_bec291de192ca44f

When hooking up a JVC KD-S36 AM/FM radio to my electric 36 V golf cart the radio will not turn on. I have power going to the red and yellow wire, and all the fuses are good

Are you routing only 12volts to the radio, some tuner if it does not burn them up to high of voltage won't allow it to power up to keep from damage it

Can I pair my android with JVC KDR336 without adaptor?

It is Bluetooth ready WHEN you connect the adapter. It says in the manual. Have a look here, and if I Google the adapter, everyone is sold out. https://www.crutchfield.ca/S-lvBqk6S0P4E/p_105KSBTA10/JVC-KS-BTA100.htmlFor Bluetooth operations, it is required to connect the Bluetooth adapter, KS-BTA100 (not supplied) to the auxiliary input jack (R-AUX/BT ADAPTER) on the rear of the unit.

My JVC KD-R426 keeps on saying warning check wiring and reset system. I've tried everthing but it still does the same. What must I do

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.
