How to find Honda HR-V 2020 radio serial number

How to Get Your 2020 Honda HR-V Radio Code

Car radios use security codes tied to the radio unit itself instead of the model or production year.

  • The system uses the HR-V's radio serial to retrieve the unlock code.
  • When you input the serial into the generator, the system identifies the radio unit and retrieves the corresponding code.
  • Simply input the digits into the HR-V stereo.
  • The online process is quicker and more accessible than visiting the Honda dealer.

How to Enter the Radio Code

When you obtain the correct unlock code based on the S/N, you can restore default functionality by entering it into the unit.

The code entry process depends on the control layout, but most 2020 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 SAFE displayed on screen.

Step-by-Step - The Correct Way to Enter It

To enter the code on the 2020 Honda HR-V:

  1. Ignition ON. Radio shows "CODE" or "ENTER CODE".
  2. Non-touchscreen models: Press preset buttons 1-5 to cycle to each digit, then hold button 6 to confirm.
  3. Display Audio touchscreen: An on-screen keypad appears. Enter each digit and press "Enter" or "OK".

Lockout: 3 wrong codes trigger a 60-minute lockout. Keep ignition ON. Do not cycle the key or the timer starts over.

Entering the unlock code on a 2020 HR-V radio

  1. Switch the ignition to ON and power the audio unit so the CODE or ENTER CODE prompt is shown on the 5-inch LX screen or the refreshed 7-inch Display Audio screen on Sport, EX, EX-L and Touring.
  2. 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.
  3. 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 added in 2019 is for audio volume only and is not part of the code-entry sequence.
  4. If the unit reactivates itself when battery power is restored, that is the documented Honda audio reactivation behavior referenced in the owner's manual and no separate code entry is required.
  5. 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 can be accepted.

Can't Locate Your Radio Serial Number? Follow These Steps for Honda HR-V 2020

The important thing to know is that factory radios use a specific serial number to identify each unit.

Your security system links the code directly to this serial.

Different from car-specific data such as VIN or registration info, it is not determined by the model or production year, so you'll be able to retrieve it even if you have a radio that you bought afterwards.

Depending on the manufacturer and radio installed in your Honda HR-V, the retrieval method varies.

These are the best ways to find it.

Factory radios fitted to the 2020 Honda HR-V

  1. 5-inch color audio system on the LX trim, controlled by physical buttons and a volume knob, with AM/FM, Bluetooth HandsFreeLink, a single USB input and a 4-speaker layout.
  2. Refreshed 7-inch Display Audio touchscreen on Sport, EX, EX-L and Touring trims, with the physical volume knob restored in 2019 carried forward, reconfigured icons, two USB ports and a 6-speaker layout that adds tweeters to the basic LX configuration.
  3. Apple CarPlay and Android Auto are standard on Sport and higher trims as part of the refreshed Display Audio software, paired with HondaLink for additional connected services.
  4. EX-L pairs the 7-inch Display Audio with HD Radio and an upgraded interior, while Touring sits at the top of the line-up with Honda Satellite-Linked Navigation, voice recognition, 3D landmarks and a higher-resolution map experience built into the same head unit.
  5. The 1st gen HR-V audio system in the US market 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.

Accessing the Serial Number Through the Radio Menu

These are the steps you should follow for 2020 Honda HR-V:

The 2020 Honda HR-V may feature Honda's Display Audio touchscreen (7" depending on trim) or a base non-touchscreen radio. Both types support serial number display via the 1+6 button method:

  1. Turn ignition to ON. Let the radio to turn on. The screen shows "CODE" when locked.
  2. Simultaneously press preset buttons 1 and 6 for 3-5 seconds.
  3. The serial number appears in two halves (e.g., U3210 + L0482).

Also: On 2020 HR-V with the Display Audio touchscreen, navigate to Settings → System → Device Information – the serial may be listed there without using the button combination.

Reading the serial on a 2020 HR-V factory radio

  1. Switch the ignition to ACC or ON but leave the audio unit powered off so the dash is live without the radio playing.
  2. Press and hold preset buttons 1 and 6 together on the audio unit's preset row.
  3. While still holding 1 and 6, press the radio power button to wake the unit; on the LX 5-inch unit the service screen used to display the serial is widely reported to appear, while on the refreshed 1st gen HR-V Display Audio the on-screen path is less consistently documented in HR-V-specific sources.
  4. Where the screen appears, record the four characters shown after the letter U on the first screen, then wait for the display to alternate and record the four characters shown after the letter L on the second screen.
  5. Concatenate the two halves in order to obtain the 8-character serial; the U and L letters are screen prefixes and are not entered into Honda's lookup.
  6. If no serial screen appears on the 7-inch Display Audio, the value can be read from the chassis label exposed during removal, or pulled by a Honda dealer using the HDS scan tool through the diagnostic connector; if the unit reactivates itself when battery power returns, the documented Honda audio reactivation behavior applies and no serial-based lookup is needed.

Manufacturer Label Inspection

If the serial number cannot be accessed on-screen, use the pull-out method.

Most Honda HR-V original radios include a tag with the serial number printed on the chassis.

Steps:

  1. Power down the vehicle.
  2. Remove the dashboard frame surrounding the radio.
  3. Loosen the fasteners.
  4. Pull the unit slightly out to access the label.

The serial number is usually located near the manufacturer sticker.

If none of these methods display the serial on the 2020 Honda HR-V:

  1. Power down the vehicle.
  2. Detach the radio surround. The 2020 HR-V's modern dashboard uses snap-fit clips.
  3. For Display Audio models: Unscrew the mounting screws (Phillips-head) securing the display module.
  4. On base trims: Remove the four screws holding the radio unit.
  5. Slide the unit out and find the serial on the sticker on the unit casing.

Note: The touchscreen unit is wider and more integrated than the base radio. Take care when extracting it.

Removing the radio on a 2020 HR-V to read the serial label

  1. Disconnect the negative battery terminal first and wait several minutes for the SRS capacitors to discharge before touching the dash.
  2. Begin 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.
  3. As the bezel lifts out, disconnect the hazard switch and any accessory harnesses on its rear and set it aside on a soft cloth.
  4. 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.
  5. Slide the audio unit straight out of the dash opening, disconnect the antenna lead and the multi-pin connectors on the rear, and read or photograph the chassis label; the printed 8-character serial should match the on-screen value where it is available.
  6. Use only plastic trim tools throughout to avoid scratching the soft-touch surround, and keep the screws sorted because lengths can differ between the trim panel and the head-unit bracket.

Typical Serial Number Examples for 2020 HR-V

Depending on the radio installed in the 2020 Honda HR-V:

  • U1234L5678 – Standard Honda OEM format
  • HBM#### – Used in Display Audio and nav-equipped units
  • 913A#### – Certain Alpine-manufactured radios

The 2020 HR-V may have: base CD radio (U/L format), Display Audio 5"/7" (HBM format), or navigation unit (HBM format). All require a 5-digit unlock code.

Important Make sure you record the serial number, not the part number (which starts with 39100, 39101, or similar Honda part coding).

What the 2020 HR-V radio serial usually looks like

  1. The serial used by Honda's lookup is reported to be 8 characters long on the 1st gen HR-V, with most LX and Sport/EX/EX-L/Touring units returning a numeric value.
  2. 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 U and L letters are screen labels rather than part of the value submitted to Honda.
  3. A representative format reads U1234 followed by L5678, corresponding to a stored serial of 12345678 for the lookup.
  4. Some chassis labels include 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.
  5. If the printed label and the on-screen value 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.

What Caused the Radio to Lock?

Honda's Display Audio system uses the same anti-theft architecture as earlier radios: losing battery power activates a code request at next startup. This affects both the non-touchscreen radio and the Display Audio touchscreen.

  • Battery replacement — the usual culprit.
  • Battery disconnect during repairs — any work that interrupts battery power will re-engage the lock.
  • Completely dead battery — a drained battery has the same result.

Note: a number of higher-trim Display Audio models from this era do not use a traditional code-based lock — if the radio never prompted for a code after losing power, it may use a different anti-theft method tied to the vehicle VIN.

HR-V 2020 Common Radio Problems

For Display Audio-era Honda radios, a rejected code is typically caused by the serial was taken from the wrong source. Both the button method and the settings menu can produce the correct serial — confirm that the serial you submitted came from the radio itself and not from an online database.

If the code was already entered once and rejected, stop and reach out before trying again — a second wrong attempt gets you one step 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 press and hold button 6 to confirm — same as older Honda platforms.
  • Display Audio 5" or 7" touchscreen: An on-screen numeric keypad is shown when the code prompt is active. Enter the digits and press OK or Enter on screen.

Should the touch input not work, try the physical preset buttons — certain units support either input method. Make sure the screen is fully powered on before attempting entry.

The Display Audio era includes radios using different serial formats depending on which unit was fitted:

  • U####L#### — base CD radio serial (10 characters, two halves).
  • HBM#### — Display Audio 5"/7" and navigation units.
  • 913A#### — some Alpine OEM configurations.

Part numbers printed nearby begin with 39100 or 39101 — do not submit these. If uncertain, use the Settings → Device Information menu or the 1+6 button method to display the serial directly from the unit.

If the Display Audio screen powers on but shows the home screen without a "CODE" prompt, consider these points:

  • The radio may not be locked — some 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.
  • Check the Settings → System → Device Information route; if the serial is visible there, the unit could still be functional without a code.

If none of these apply, checking the radio fuse is the next step — a blown fuse prevents the radio from showing any display at all.

The Display Audio platform uses the same three-try lockout as earlier Honda radios. Recovery steps:

  1. Keep the ignition in ON or ACC — do not switch off.
  2. Allow the full 60-minute period. The touchscreen may go to sleep during this time — this is expected.
  3. After 60 minutes, the code prompt returns and you can.

For touchscreen units, the lockout countdown operates even when the screen is off. Just leave the vehicle running or the ignition on ACC for the full hour.
