MAN truck radios unlocked online — calculated from the Bosch serial on the casing.
MAN cabs use Bosch head units whose code is calculated from the serial printed on the casing.
The unit has to come forward out of the dash to read the label.
Thirteen digits, beginning 0 and ending 00 — copy them exactly.
The rule has no confirmation from a MAN owner yet, so the code is free: a share unlocks it and we ask whether it worked.
