Changing the time on your JVC car radio is typically a straightforward process done through the head unit's settings menu. The exact steps can vary slightly by model, but the general procedure involves holding the "DISP" or "CLOCK" button until the display blinks, then using the tuning or volume knob to adjust the hours and minutes. For newer models with RDS (Radio Data System), the time may set automatically if the feature is enabled.
The most reliable method is to consult your specific model's owner's manual. However, if you don't have it handy, here’s a general guide that works for many JVC receivers like the KD, KWR, and KW series.
Step-by-Step Guide:
Automatic Time Setting (RDS): Many modern JVC units can sync time automatically via RDS broadcasts from FM radio stations. To enable this, navigate to the Settings Menu, find the "Clock" or "Time" option, and look for an "Auto Set" or "RDS" setting. Turn this feature on. This is the most convenient method as it adjusts for Daylight Saving Time and ensures accuracy.
| JVC Model Series | Common Time-Setting Method | RDS Auto Time Setting Available? |
|---|---|---|
| KD Series (e.g., KD-R996, KD-SR86) | Hold "DISP" button, use tuning knob | Yes, on most models |
| KWR Series (e.g., KWR-940) | Hold "CLOCK" button, use volume knob | Yes |
| KW Series (e.g., KW-M865BW) | Via Touchscreen Settings Menu | Yes |
| Older Single-DIN Models | May require a small "Reset" button | No |
| KD-T Series | Hold "DISP" button, use navigation keys | On select models |
If these methods don't work, a temporary fix is to disconnect the car battery for a minute and reconnect it, but this will reset all your station presets. Searching online for your specific model number followed by "set clock" will often yield a video tutorial.

Honestly, I just kept pressing every button until something worked. On my JVC, I found that if I press and hold the "DISP" button for a few seconds, the numbers start flashing. Then I twist the big knob on the front to change the hour, hit "DISP" again to jump to the minutes, twist the knob again, and then just wait. It sets itself after a moment. Took me a couple tries to get the hang of it, but it's not too bad once you know which button to hold down.

The easiest way is to let the radio set itself. Look in your settings menu for an option called "RDS Clock" or "Auto Time." Turn that on. The radio will grab the correct time from special FM station signals. It’s a set-it-and-forget-it feature that automatically handles the switch for Daylight Saving Time, so you never have to worry about being an hour off again. Manual adjustment should be your last resort if you're in an area with a weak FM signal.
