UNLOCK YOUR RADIO.
WE'LL FIND THE RIGHT CALCULATOR.

You do not need to know who manufactured your radio. Find the serial number, enter what you see below, and DUBB45 will point you to the correct calculator.

FIND MY CALCULATOR
STEP 01

FIND YOUR SERIAL NUMBER

Look for SERIAL, S/N, or a code beginning with letters such as TM9, T0MYD, T00BE, TxxQN, or TxxAA. It may be in the radio settings or printed on the radio label.

STEP 02

TYPE WHAT YOU SEE

Paste the whole serial if you have it. The finder only uses the serial pattern to choose the correct calculator.

OR CHOOSE VISUALLY

MATCH THE BEGINNING
OF YOUR SERIAL

The large red characters are what matter. You don't have to identify the radio by appearance.

STILL NOT SURE?

DON'T GUESS.

Wrong calculator = wrong code. Use this quick decision guide before entering anything into the radio.

01Does the serial start with TM9?

FCA vehicle → TM9 calculator. Maserati → Maserati TM9 calculator.

02Does it start T0MYD?

Use Delphi T0MYD. Enter the complete serial.

03Does it start T00BE?

Use Harman / Becker. Enter the required final digits.

04Do you see QN in TxxQNxxxx?

Use Continental VP2 / TQN.

05Do you see AA in TxxAAxxxx?

That is an Alpine-style serial. Use the Alpine calculator from the Radio Codes menu.

06None of these match?

Send us the full serial number and part number. We'll identify it.

CAN'T IDENTIFY IT?

SEND US THE LABEL.

Take a clear photo of the radio sticker or send the full serial and part number. We'll help you choose the correct calculator instead of guessing.

QUICK ANSWERS

BEFORE YOU START

Where do I find the radio serial number?

Check Settings → System Information first. If it is not displayed, the OEM label is normally on the top, side, bottom, or rear of the radio chassis.

Are these calculators actually free?

Yes. DUBB45's listed radio-code calculators are free to use with no account, credit card, or software installation.

Why did my radio suddenly ask for a code?

This commonly happens after battery replacement, a dead battery, power loss, radio removal, radio replacement, or installation of a used unit.

Should I keep trying codes if one doesn't work?

No. Verify the serial and calculator type before repeated attempts. Some radios enter a timed lockout after incorrect codes.
