Can't Locate Your Unit's S/N? Follow The Steps Below for Honda HR-V 2022
The initial step is to find and write down the radio's S/N.
Based on the head unit type used in your 2022 HR-V, the serial can usually be found either through the display menu or by checking the label on the radio itself.
Follow the steps below to identify your S/N the right way.
Factory radios fitted to the 2022 Honda HR-V
The 2022 model year is the run-out year for the 1st gen HR-V in the US market and carries the same audio line-up as 2020 and 2021. The LX trim continues with the 5-inch color audio system, controlled by physical buttons and a volume knob and driving a 4-speaker layout. Sport, EX, EX-L and Touring keep the refreshed 7-inch Display Audio with the physical volume knob restored in 2019, Apple CarPlay and Android Auto integration, two USB ports and a 6-speaker layout that adds tweeters to the basic LX configuration. EX-L adds HD Radio and interior upgrades, while Touring layers in Honda Satellite-Linked Navigation, voice recognition, 3D landmarks and a higher-resolution map experience on the same head unit family. The audio system in the US-market 1st gen HR-V is tied into Honda's anti-theft strategy, although the owner's manual documents an audio reactivation procedure that allows the unit to re-establish a connection with the vehicle control unit when the audio control unit comes back up in the same car.
Using Hidden Radio Menus to Find the Serial
The method for 2022 Honda HR-V is this:
The 2022 Honda HR-V may feature Honda's Display Audio system (7" depending on trim) or a base non-touchscreen radio. All versions support serial number retrieval via the 1+6 button method:
- Turn ignition to ON. Let the radio to boot. The screen shows "CODE" when locked.
- Simultaneously press preset buttons 1 and 6 for about 5 seconds.
- The serial number appears in two halves (e.g.,
U3210+L0482).
Alternative: On 2022 HR-V with the Display Audio touchscreen, check Settings → System → Device Information – the serial may be listed there without using the button combination.
Reading the serial on a 2022 HR-V factory radio
The serial-display procedure on the LX 5-inch unit follows the standard US-market Honda audio path: turn the ignition to ACC or ON with the audio unit powered off, press and hold preset buttons 1 and 6 together, then press the radio power button while still holding the two presets to wake the unit into the service screen. Where the screen appears, it alternates between a screen prefixed with U followed by four characters and a screen prefixed with L followed by four characters; recording both halves and concatenating them in order yields the 8-character serial used by Honda's lookup. The U and L are screen labels rather than part of the value entered. On the refreshed 7-inch Display Audio used by Sport, EX, EX-L and Touring, the on-screen path has not been independently confirmed across multiple HR-V-specific sources for the 1st gen platform, so the chassis label exposed during removal is the more reliable physical reference, and a Honda dealer reading via the HDS scan tool through the diagnostic connector remains a documented fallback. If the unit reactivates itself when battery power returns, the documented Honda audio reactivation behavior applies and no serial-based lookup is needed.
Taking Out the Radio to Access the S/N on the Tag
If the serial does not appear in menu, the next step is checking the radio itself.
Many Honda radios require physical access to the ID label attached to the unit.
Typical approach:
- Start by completely shutting off the engine - pull the key out.
- Then lift the radio surround.
- Next, loosen the mounting points and slide the radio forward.
- Look for a barcode label showing the serial number.
If none of these methods work on the 2022 Honda HR-V:
- Turn off the vehicle.
- Remove the dashboard trim. The 2022 HR-V's integrated dashboard uses plastic clips.
- On touchscreen trims: Unscrew the fasteners (Phillips-head) securing the display module.
- On base trims: Unscrew the 4 Phillips screws holding the radio unit.
- Ease the unit out and find the serial on the label on the back or side.
Tip: The touchscreen unit is larger and more integrated than the standard radio. Take care when extracting it.
Removing the radio on a 2022 HR-V to read the serial label
The 2022 HR-V uses the same dash architecture as the rest of the 1st gen line, so the removal sequence is unchanged across the model run. Begin by disconnecting the negative battery cable and waiting several minutes for the SRS capacitors to discharge before working in the dash. Start at a lower corner of the center bezel that surrounds the audio unit and climate controls and pull rearward with plastic trim tools to release the perimeter clips; the 1st gen HR-V uses clip-retained trim rather than visible screws around the head unit, so work evenly around the panel so no clip is over-stressed. As the bezel lifts out, disconnect the hazard switch and any accessory harnesses on its rear and set the panel aside on a soft cloth. Remove the screws that secure the audio unit bracket to the dash frame, supporting the head unit from underneath as the last fastener is freed so it does not drop. Slide the audio unit out of the dash opening, disconnect the antenna lead and the multi-pin harnesses on the rear, and read or photograph the chassis label; the printed 8-character serial should match the value returned by the on-screen procedure where it is available. Use only plastic trim tools throughout to avoid marking the surround, and keep the screws sorted because lengths can differ between the trim panel and the head-unit bracket.

Common S/N Formats Used on 2022 HR-V Units
Based on the radio fitted to the 2022 Honda HR-V:
U1234L5678– Classic Honda OEM formatHBM####– Found on Display Audio and navigation units913A####– Some Alpine-manufactured units
The 2022 HR-V may have: base CD radio (U/L format), Display Audio 5"/7" (HBM format), or navigation unit (HBM format). All use a 5-digit unlock code.
Important Verify you record the serial number, not the part number (which starts with 39100, 39101, or similar Honda part coding).
What the 2022 HR-V radio serial usually looks like
The 1st gen HR-V factory radio is reported to use the same 8-character alphanumeric serial format as other US-market Honda Display Audio units, and on most 2022 units the value is numeric. Where the on-screen procedure works, the first half is shown after the letter U on screen one and the second half after the letter L on screen two; the letters themselves are screen labels that should not be entered into Honda's lookup tools. A representative format reads U1234 followed by L5678, which corresponds to a stored serial of 12345678 for the lookup. Some chassis labels carry a longer alphanumeric string with a manufacturer prefix on the printed sticker; the 8 characters that match the on-screen U and L pair are the ones used for the lookup. If the printed and displayed serials disagree, the on-screen value is generally the one accepted by the official Honda radio code portal, with the chassis label retained as a fallback when the service screen cannot be triggered.
Unlock Your 2022 Honda HR-V Radio in Minutes - How It Works
- Skip long troubleshooting discussions or service visits - you can find the code online using the radio serial number.
- Identify the serial number. It is always present on the unit itself, and sometimes you can see it on the HR-V's radio screen.
- Type it into the field above, and the software will retrieve the correct 2022 HR-V unlock code.
- After receiving your code, type it in using HR-V's radio controls to unlock the system successfully.
- The entire process takes just a short moment and requires zero paperwork and no dealer visit.
How to Enter the Radio Code
After generating the correct unlock code based on the serial number, you can restore normal functionality by entering it into the unit.
The code entry process depends on the head unit design, but most 2022 HR-V systems follow a similar structure using preset buttons, touch controls, or rotary knobs - depending on if it's a factory or an aftermarket unit.
You will typically see ENTER CODE displayed on screen.
Step-by-Step Code Input Guide
To input the code on the 2022 Honda HR-V:
- Ignition ON. Radio shows "CODE" or "ENTER CODE".
- Non-touchscreen models: Use preset buttons 1-5 to select each digit, then press and hold button 6 to confirm.
- Display Audio touchscreen: An on-screen keypad appears. Enter each digit and press "Enter" or "OK".
Lockout: Three wrong entries trigger a 60-minute lockout. Leave ignition ON. Do not cycle the key or the timer starts over.
Entering the unlock code on a 2022 HR-V radio
If a CODE or ENTER CODE prompt appears after a power-loss event, switch the ignition to ON and power the audio unit so the prompt is shown on the 5-inch LX screen or the refreshed 7-inch Display Audio screen on Sport, EX, EX-L and Touring. On the LX 5-inch unit, use preset buttons 1 through 5 to set each digit of the 5-digit code in order, pressing each preset the number of times required for that digit, then submit by holding preset 6. On the refreshed 7-inch Display Audio, the 5-digit code is tapped on the on-screen number pad and confirmed with the on-screen ENTER soft key once the full code is visible; the physical volume knob is for audio volume only and is not part of the code-entry sequence. If the unit reactivates itself when battery power is restored, that is the documented Honda audio reactivation behavior described in the owner's manual and no separate code entry is required. Repeated wrong entries trigger a temporary lockout that requires the ignition to be left in the ON position for about an hour before another attempt is accepted.
HR-V 2022 Common Radio Problems
The Display Audio platform applies the same 3-attempt lockout as older Honda radios. To exit lockout:
- Keep the ignition in ON or ACC — avoid turning it off.
- Allow the full 60-minute period. The touchscreen might dim during this time — this is expected.
- After 60 minutes, the radio re-displays "CODE" and you can.
On Display Audio touchscreen models, the lockout countdown runs in the background. Simply leave the vehicle running or the ignition on ACC for the full hour.
The Display Audio era includes radios using multiple serial prefixes depending on the trim level:
U####L####— base CD radio serial (10 characters, two halves).HBM####— Display Audio 5"/7" and navigation modules.913A####— certain Alpine OEM configurations.
Part numbers printed nearby start with 39100 or 39101 — do not submit these. When in doubt, use the Settings → Device Information menu or the 1+6 button method to display the serial directly from the unit.
For Display Audio-era Honda radios, a rejected code is typically caused by the serial was misread. Either retrieval method can produce the correct serial — double-check that the serial you submitted was read off the radio itself and not from an online database.
After one failed entry, stop and contact support before trying again — a second wrong attempt brings you closer to the 60-minute lockout. A no-charge serial reverification can be done on request.
Code entry depends on the specific radio in the Display Audio-era HR-V:
- Non-touchscreen base radio: Use preset buttons 1–5 to cycle to each digit, then hold button 6 to confirm — identical to older Honda platforms.
- Display Audio 5" or 7" touchscreen: An on-screen numeric keypad appears when the code prompt is active. Tap each digit and press OK or Enter on screen.
Should the touch input not work, attempt the physical preset buttons — some units accept both input method. Ensure the screen is fully powered on before attempting entry.
If the Display Audio screen powers on but shows the home screen without any "CODE" prompt, consider these points:
- The radio may not be locked — certain battery changes don't trigger the lock if done quickly enough.
- Certain Display Audio units, the code prompt shows only on the audio portion of the screen, not the navigation display — wait a moment after startup.
- Try the Settings → System → Device Information route; should the serial appear, the unit could still be functional without a code.
Should none of the above match, checking the radio fuse is the next step — a failed fuse prevents the radio from showing any display at all.
Why Is the Radio Asking for a Code?
Honda's Display Audio system retains the same anti-theft architecture as earlier radios: losing battery power causes a code request at next startup. This affects both the non-touchscreen radio and the Display Audio touchscreen.
- Battery replacement — by far the most frequent cause.
- Battery disconnect during repairs — any work that cuts battery power will activate the lock.
- Completely dead battery — a fully discharged battery has the same result.
Worth knowing: many higher-trim Display Audio models from the 2014–2021 period do not use a traditional code-based lock — if the radio never showed "CODE" after a battery change, it could have a different anti-theft method linked to the vehicle VIN.
