Honda & Gathers & Blaupunkt Radio Code Finder (All Models)

How to Find Your Radio Serial Number?

Method 1: 2001 and Newer Models (Via Display)

If your Honda is newer than 2001, you can usually retrieve the serial number without removing the unit:

• Step 1: Turn the ignition key to the ON position.
• Step 2: Turn on the radio and wait for the “CODE” message to appear on screen. (If it doesn’t appear, remove the radio fuse for 1 minute, reinsert it, and return to Step 1.)
• Step 3: Turn the unit off.
• Step 4: While holding down buttons 1 and 6 on the radio panel, turn the unit on.
• Step 5: The display will alternate between U (showing the first 4 digits of the serial number, e.g. U2200) and L (showing the last 4 digits, e.g. L0055).
• Step 6: Note down the number exactly as shown and enter it into the lookup tool. The system will recognize it automatically.

💡 Alternative Format: On some units, the serial number may appear all at once, such as 40047239 or AHH27001589.

Method 2: Honda Accord (2003 – 2007 Special Method)

• Step 1: Turn the ignition key to the ACC (I) position.
• Step 2: Turn on the radio and wait for the “CODE” message to appear. (If it doesn’t appear, remove the radio fuse for 1 minute, reinsert it, and return to Step 1.)
• Step 3: Turn the unit off.
• Step 4: Press and hold the upper halves of the SEEK/SKIP and CH/DISC buttons, then press and release the PWR/VOL knob.
• Step 5: The display will alternate between U (first 4 digits, e.g. U2200) and L (last 4 digits, e.g. L0055).
• Step 6: Note down the number exactly as shown and enter it into the lookup tool below. The system will recognize it automatically.

Method 3: Pre-2001 Models or Units with Non-functional Display (Label)

If your vehicle is older than 2001 or the display does not show the serial number, you will need to remove the unit:

• Locate the label on the side or top of the unit and find the section marked “Serial No”.
• Example formats: HLB22033893B, GGZ22019674, 30009030, BP5022S0692058, KNT29000239, 9139Y196, 987B7421, 947GR361 — note the number exactly as it appears.
• Once you have the number, use the online lookup tool below.

Method 4: Navigation (Navicode) Serial Number

The serial number of your navigation unit is located in a different place than the radio unit:

• The number is found on the navigation unit in the trunk or on the label on the control panel where the removable DVD is located.
• It is usually 8 digits long (e.g. 12345678); sometimes it may have 3 letters at the beginning (e.g. ABC12345678).
• If you have your navigation serial number, the navicode can also be queried through the same lookup tool.
