Free Maserati Quattroporte Radio Code

Every Maserati Quattroporte from 2003 to 2021: which radio was fitted, where its serial number hides, and what we can do with it.

Your code comes from the serial number of the radio, not from the car — so the first job is getting that number off the unit. The table below is your Quattroporte: the units fitted, and where the serial hides on each.

Already have the serial? Type it in and we will tell you straight away whether we can answer it.

Enter Your Serial No:

Becker Model No.:

On the same label as the serial: BE and four digits, for example BE 4715.

What does your radio ask for?

Only needed for a Becker unit — an 8-character serial. Look at the display and count the dashes it shows for the code; if it wants five digits, count the numbered buttons you actually press to enter them, not the ones on the panel.

That does not look like a Maserati serial — check the table below for where to find it.

We never ask for the code you are missing — only the serial.

Which radio is in your Quattroporte?

Generation	Radios fitted	Serial	Where to read it	What we do
M139/M156 2003–2021	Bosch, Becker, Harman 8.4 touchscreen	5 digits / T00BE…	the five-digit number on the unit label; on the 8.4-inch Harman touchscreen the whole T00BE serial	Free in 24 h, or instant if you pay

Radio names are what is written on the fascia, not the name of the company that built the unit — a “6000 CD” or an “RCD 300” is what you see in the car. Unit fitment varies by market and trim, so treat the list as the usual case and let the serial decide: it is the serial that determines the code, not the model.

Maserati Quattroporte radio code by year

From 2003 to 2021 the Quattroporte came with the radios below; the serial on the unit is what decides the code.

Maserati Quattroporte M139/M156 radio code (2003–2021)

On Quattroporte cars from 2003–2021 the radio fitted was usually one of: Bosch, Becker, Harman 8.4 touchscreen. The serial reads 5 digits / T00BE…; the five-digit number on the unit label; on the 8.4-inch Harman touchscreen the whole T00BE serial. Send us that serial: the code is free by email within 24 hours, or on the page straight away if you pay to skip the wait.

How to enter the code in your Quattroporte

Quattroporte and GranTurismo with the Bosch navigation screen: set each digit with the rotary knob below the display — owners report the on-screen keypad does not take the code.
Ghibli and Levante (8.4-inch touchscreen): type the four digits on the screen and press OK if it appears.
Becker units (3200 GT, Coupé, Spyder): enter the five digits on the buttons beneath the screen, in order.
Some units start by themselves after the last digit; others need a confirm key. If nothing happens after the last digit, tell us what the display shows rather than pressing other buttons.

Maserati Quattroporte V navigation radio: set the code with a rotary knob below the screen, not with the number keys shown on the screen; which of the two knobs is not documented

Digit keys

Careful: most units lock for good after about ten wrong attempts. If a code does not take, stop and email us before trying again.
