Maserati head units unlocked online — from the short serial on the unit’s casing.
The Panasonic-built units Maserati fitted ask for a code once power has been lost, and the number they are keyed to is a short one: five digits on the casing label.
The unit has to come forward out of the dash to read it.
Five digits, nothing else — if the number you are looking at is longer, it is a part number rather than the serial.
We hold the full table for this family, but no Maserati owner has confirmed a code to us yet, so it is free: a share unlocks it and we ask you whether it worked.
