Nissan radios unlocked online in minutes — the Bosch BP label is answered on the spot; Connect, Daewoo and Clarion we cannot decode yet, and the page says so before you start.
Nissan Connect (screen only): enter a wrong code 3 times — on the third try the radio locks for 60 minutes and shows a screen with the device number, serial number and date. Copy all three, but read the card below before you do: Connect is the one family here marked not yet. Those numbers we cannot turn into a code today, and we would rather say it on this page than after you have left your email.
Nissan Daewoo: the details can show on the front display, but the label on the back of the radio is more reliable — pull the unit and copy the serial, Prod No. and date from the label.
Clarion units: these are the second family here marked not yet. You can recognise one by the PN-3000P-A style number on its label — that is the device number, not a serial, and the CL serial beside it is one we cannot turn into a code today either. We would rather say so on this page than after you have taken the dash apart.
Micra K12 and older (Bosch): the label serial starts with BP and runs 14 characters, for example BP538469472624. That one we answer on the spot, and nothing else is needed — no device number, no date.
14 characters starting BP — the whole label serial, nothing else:
BP538469472624
Three wrong codes → 60-minute lock screen with the device number, serial and date.
Serial, Prod No. and date from the label on the back of the casing.
A label carrying a PN-3000P-A style number is a Clarion. Neither that number nor the CL serial next to it gives us a code today — this family is not one we have worked out.
CL serial + PN number; K12 and older use a BP serial.
