Which radio is in your Honda Factory Radio?
Honda fitted different radios over the years. Find your Factory Radio’s years below, but go by the serial: radios are often swapped, and the free check reads it for you.
What is printed on the label
People look these up because they are the only numbers on the radio that mean anything. A part number identifies the unit and is the same on every one ever built; the serial is yours alone and is the one we need. They are easy to mix up, so here is what to expect on a Honda Factory Radio.
| Printed on the unit | What it is |
|---|---|
| U2154 L2135 | The two screens together. The serial is the eight numbers: 21542135. |
| B30001930 | The glovebox label. The B is a label marker, not part of the serial. |
| 30001930 | The serial as printed on the unit itself. Eight numbers. |
| GNB22005937 | Three letters and eight numbers is a navigation unit, not the radio. |
A part number on its own cannot produce a code — every radio of that model shares it. If the number you have is one of the part numbers above, keep looking for the serial: it is the longer one, and usually on a separate line or a barcode label.
How to find your Honda Factory Radio radio serial number
Most Honda Factory Radio radios show their serial on the screen, so you don’t need to take anything apart. The serial tells us exactly which code your radio needs.
On the screen
- Check the handbook wallet for the anti-theft card first.
- Turn the ignition on and leave the radio off. Hold buttons 1 and 6, then press the power button. Two numbers appear, one starting U and one starting L: write both down. The letters are only labels for the top and bottom halves — the numbers together are the serial.
- Touchscreen (2013 on): go to Settings, then System, then Detailed information.
- Older sat nav cars (2003–2012): hold MAP/GUIDE, MENU and CANCEL together.
- Nothing on screen? Look inside the glovebox door: dealers were asked to stick a label there with the serial on it, written as a B and then eight numbers.
- Off a label, the numbers may sit behind three letters or a B, and sometimes there is one more letter after them. Type the lot — we take the serial out of it.
On the label
The serial is also printed on a label on the top or side of the radio. Most radios slide out with a pair of radio removal keys (a few pounds from any car parts shop). Push them into the slots on the front until they click, then ease the radio forward. Some have screws to undo first.
Take a photo of the label rather than copying it by hand: it’s easy to mix up 0 and O, or 1 and I.
Tips for your Honda Factory Radio
- Ignition on with the radio off, hold buttons 1 and 6 and press power. Two screens appear, one starting U and one starting L.
- A single letter after the numbers is not part of the serial at all — leave it off.
- From 1998 dealers were asked to put a label inside the glovebox door, written as a B and then eight numbers.

How to enter your Honda Factory Radio radio code
Once you have your code, key it in like this. The example below shows the button presses. Your order page shows the same steps next to your code.
Honda
- Most codes are 5 numbers. Press the button with each number on it, once.
- Touchscreens: use the on-screen keypad and press ENTER.
If your Honda Factory Radio radio says LOCKED, WAIT or SAFE
Each wrong code makes the radio wait longer before the next try, and some radios lock for good after too many. Don’t guess: get the right code first, then follow the steps for your radio.
| Radio | What to do |
|---|---|
| Honda | ERR — leave the ignition on for 1 hour. |

Why we use your radio’s serial, not your number plate
A radio code belongs to the radio, not the car. A dealer usually looks it up from the Honda Factory Radio’s number plate or VIN (the 17-character number in your logbook), which only works if the car still has the radio it left the factory with. Radios are often swapped under warranty, upgraded, or changed by a previous owner.
The serial number is printed on the radio itself, so the code we give you matches the radio in front of you. It is also how we can check it for free before you pay. Main dealers often charge £30–£130, and you usually have to book the car in.
Honda Factory Radio radio code questions
Do I type the U and the L?
Type both screens in. The letters only label the top and bottom halves; the eight numbers together are your serial, and we drop the letters for you.
My serial has three letters in front.
Then it is a navigation unit rather than the radio. We do those too, on our Honda sat nav page.
How much is a Honda Factory Radio radio code?
£9.99 per code. The free check comes first, so you only pay once we know we can do it, and you get your money back if the code doesn’t work.
How long does it take?
Our team looks your code up and emails it within 2 hours.
What if the code doesn’t work?
Check the serial first: 0 and O, or 1 and I, are easy to mix up. Still stuck? Tell us from your order page and we’ll put it right or refund you in full.
