Where to Find the Serial Number on your HR-V
The first step is to locate the radio's serial num.
Based on the head unit type fitted in your 2024 HR-V, the serial can be accessed either through the display menu or by pulling the unit out and checking the label on the radio itself.
Follow the steps below to identify your S/N the right way.
View Your Serial Number via the Radio Display
Try the following for your 2024 Honda HR-V:
The 2024 Honda HR-V features Honda's newest infotainment system with a larger touchscreen. The serial number can be retrieved via the infotainment menu:
- Turn ignition to ON.
- Navigate to: Settings → System → Device Information or System Information.
- The serial number is typically shown on this screen.
Alternative: The traditional buttons 1+6 method can be tried if the settings menu doesn't show the serial. Hold buttons 1 and 6 for 3-5 seconds while the radio shows "CODE".
Check it by Pulling Out the Radio Unit
If the serial number cannot be accessed via display, use the pull-out method.
Most Honda HR-V original radios include a sticker with the serial number printed on the housing.
Basic process:
- Disable power.
- Gently detach surrounding panel pieces.
- Release clips holding the radio.
- Move slightly to inspect the label.
If on-screen methods don't work on the 2024 Honda HR-V:
- Turn off the vehicle.
- Pry off the dashboard trim panel around the touchscreen. Newer Honda vehicles use tightly-fitted trim with snap clips.
- Unscrew the fasteners securing the infotainment unit.
- Slide the unit forward to access the serial label on the side of the module.
Caution: Modern Honda infotainment units are tightly mounted into the dashboard. Attempt the on-screen method first.

How Serial Numbers Usually Look on These HR-V Radios
The 2024 Honda HR-V uses Honda's current infotainment system. Serial number formats:
HBM####– Primary format for newer Honda infotainment unitsU1234L5678– May still appear on some lower-trim radio configurations
The 2024 HR-V's audio system is sourced from Honda's OEM supplier (Alpine). The serial is typically 8 to 10 characters long.
Note Some 2024+ HR-V trims may use Android-based infotainment that may not require a traditional radio code. If your radio never displayed "CODE" after a battery disconnect, it may no longer be code-locked.
Code Entry Process for 2024 HR-V
Once the system gives you 2024 Honda HR-V unlock code from the S/N, you're ready to reactivate the radio.
Many drivers hesitate at this stage because input process can look different across radio versions, but it's usually simple.
When the radio shows CODE, it means the unit is waiting for the correct numbers.
In-depth Input Instructions for HR-V 2024
To input the code on the 2024 Honda HR-V:

HR-V 2024 Common Radio Problems
After 3 incorrect code entries, the modern Honda infotainment enters a 60-minute lockout. Recovery is straightforward:
- Keep ignition ON — do not switch off the vehicle.
- Allow the full 60 minutes to elapse. The display may enter standby — this is fine.
- After the lockout period, the "CODE" prompt reappears.
If the vehicle cannot be left running for 60 minutes, ACC mode works too to keep the timer running. Do not cutting power — it resets the countdown.
On modern Honda infotainment, code entry is usually done via the on-screen keypad:
- Tap each digit of the five-digit code using the on-screen number pad.
- Press OK or Enter to submit the full code.
For trims where hardware preset buttons are still present, use buttons 1–5 for digit selection and hold button 6 to confirm — identical to older Honda platforms. When in doubt, start with the on-screen keypad.
Modern Honda infotainment typically uses the HBM#### serial format, although base radio configurations may still use the U####L#### format. The easiest way to confirm the serial is:
- Go to Settings → System → Device Information — the serial is shown on this screen.
- As a fallback, use the 1+6 preset button method while the "CODE" screen is displayed.
Part numbers — starting with 39100 — appears on the same label but is not the serial. Use only the serial retrieved via the menu or the button method.
When the newer system boots but does not display a "CODE" prompt, it's probable one of the following:
- Some trims skip the code lock — some 2022+ models rely on VIN-linked protection instead of a traditional code.
- The radio may already be unlocked — test normal radio operation to confirm.
- Check the settings menu Settings → System → Device Information — if this menu opens normally, the system may not be in a locked state.
Should this not resolve the situation, the unit may require a dealer reset — contact support with the model year for guidance.
On Honda's modern infotainment, a rejected code traces back to the wrong serial used. The serial can be pulled through Settings → Device Information — confirm that the serial you used is the same as what appears there.
Certain recent HR-V trims have switched to Google-based infotainment which doesn't use a traditional radio code. Should the unit never displayed "CODE", a traditional code might not be relevant. Reach out to confirm which type of unit is fitted.
What Caused the Radio to Lock?
Even on Honda's newest infotainment platform, the anti-theft system may trigger when the battery is replaced. The trigger is the same across every Honda generation: loss of battery power wipes the radio's authorization state.
- Battery swap or disconnect — the primary trigger.
- Dead battery from storage or neglect — a fully discharged battery has the same effect.
Important caveat: many recent Honda vehicles have moved to Android-based infotainment that does not use a conventional unlock code. If the screen never prompted for a code after a battery event, it may use VIN-based protection instead.
