How to find your Acura radio serial number
Choose the method that matches your Acura’s radio panel. The photos show examples of units and serial number formats used in Honda and Acura radios.
Photos are examples. Copy the number from your own radio, including its letters and zeros.
Number in the selected photo:
26390472
Radio with buttons 1–6
- Turn on the ignition and radio. When CODE appears, turn off just the radio, leaving the ignition on.
- Hold preset buttons 1 and 6. While holding them, turn on the radio using Power / PWR/VOL.
- Write down the number displayed. If the display alternates between U and L, join the four digits after U to the four after L. For example, U2639 and L0472 become 26390472. Keep the zero in the second group.
- Enter the eight digits in the form. If a complete number appears beside S/N, copy that number. If you cannot display it, check the code card or the label on the casing.
No CODE message? For older radios, Acura’s instructions describe removing the BACK UP fuse for one minute, then repeating the procedure. Identify the correct fuse in your vehicle’s manual first; do not remove an arbitrary fuse.
Acura TL 2003–2007
- Set the ignition to ACC (I). Turn on the radio and check that the display shows CODE. Then turn off just the radio.
- If the panel has preset buttons 1 and 6, hold them while turning on the radio. If you are using a panel with SEEK/SKIP and CH/DISC instead, hold the upper halves of both buttons, then press and release the PWR/VOL knob.
- The display alternates between U with the first four digits and L with the last four. Write down both groups and join the digits in U-then-L order, leaving out those two letters.
- Enter the eight digits in the form. This is the audio unit's serial. If the navigation system separately asks for a code, use the “Older navigation” guide to find its serial.
Choose the method by your unit’s buttons, not just the TL’s model year. If the panel differs or no serial appears, read the number from the code card or label. If CODE is missing, see the BACK UP fuse note under “Radio with buttons 1–6”. The photos illustrate the U/L display format; the panel layout depends on the radio version.
Display Audio / touchscreen
- Switch on the ignition and radio. On the appropriate panel, hold Power + MENU + day/night or Power + Eject + HOME for about 3 seconds until diagnostics appears. Use the combination that matches your unit's buttons.
- Open Detail Information & Setting → Unit Check → HMI Unit or DA Unit. Photograph Serial No. and Model. On versions without this diagnostic menu, check HOME → Info → System/Device Information → System Info.
- Exit with Back / Return. Enter the complete number from Serial No. in the form to check code availability for this unit.
Not every touchscreen system is supported by our service. Menu names and button combinations vary by unit. If your Acura’s panel does not match these instructions, read the serial from the casing label. Do not change diagnostic settings.
Older navigation
- Turn on the ignition and navigation screen. Hold MAP/GUIDE, MENU and CANCEL together for a few seconds until the diagnostic menu appears. If this combination does not work or one of the buttons is missing, try holding SETTINGS, INFO and BACK together for a few seconds.
- Select Detail Information & Setting → Unit Check → Navi ECU. If Unit Check is already available, start there. Other versions use Detail Information & Settings → Unit Check → ECU Info. Record the value beside Serial No., including every letter.
- Exit using Return / Back. Enter the serial in the form. If the menu differs or the buttons are missing, read the number from the label on the casing.
The radio and navigation system can have separate serials and codes. Navi ECU shows the navigation serial. Do not select Mem Clear or other memory-clearing options. Some versions display a number beside the code entry boxes: photograph it too, and do not confuse it with the security code.
Serial on the label
- Check the code card and any stickers in the glovebox. If the serial is missing and the screen method does not work, you need access to the label on the top, side or rear of the radio.
- Take a clear photo of the entire label. Look for SERIAL NO., Serial No. or S/N. Do not use the model or part number instead, such as a number beginning with 39100 or 39101.
- Enter the complete serial from your label, keeping letters and leading zeros. Check it character by character before submitting the form.
Serials on units fitted to Acura vehicles come in several formats: six or eight digits, letters mixed with digits, and longer strings. Do not use only the last few characters. Removal depends on the dashboard; ask a workshop for help if you are unfamiliar with the fittings.
Older Blaupunkt radios
- Check the exact Blaupunkt radio model on the panel or label. A radio fitted by a previous owner may need a different procedure from factory Acura equipment.
- Read the label or marking on the casing. Look for the complete serial starting with BP. The separate number beginning with 7 is a part number.
- Enter the full BP serial in the form. The method for entering and confirming the code depends on the exact radio model. Read the model designation from the front panel or label.
The 1–6 method does not apply to these units. Older Blaupunkt radios use different controls to set digits and confirm the code. The Dublin C30 label illustrates the BP serial format; it is not a factory Acura radio.
Other radios / Gathers
- Check the model designation on the front panel or label. Identify whether the radio or navigation system is asking for a code so you read the correct unit’s details.
- Find SERIAL NO., Serial No. or S/N on the label. Copy the complete number, keeping all letters and zeros. This also applies to Gathers, imported units and radios fitted by a previous owner.
- Enter the serial in the form. Check code availability before payment. The radio’s appearance or Acura branding alone does not confirm that its serial is supported.
Supported Gathers models: VXM-145, VXM-155, VXM-165, VXM-175, VXM-185, VXM-195, VXM-205, VXM-215. Unsupported Gathers models: VXM-142, VXM-152, VXM-164, VXM-174, VXM-184, VXM-194, VXM-204. We do not support Fujitsu or JVCKENWOOD. Do not remove letters or digits to make a serial fit the form.
Use the details from your own unit. The serial number identifies the radio — it is not the security code you enter on the radio.
