Maserati head units unlocked online — from the serial on the unit’s casing.
Maserati head units ask for a code once power has been lost. Which number you need depends on the unit.
The Harman-built 8.4-inch touchscreen fitted to the Ghibli, Levante and later Quattroporte carries a 14-character serial starting T00BE. The older Panasonic-built units are keyed to a short one: five digits on the casing label.
Either way the unit has to come forward out of the dash to read it.
Enter the whole T00BE… string exactly as printed, or the five digits — a longer number beside them is a part number rather than the serial.
The answer comes back the moment you enter the serial: free by email within 24 hours, or straight away if you would rather not wait.
