Hi, Battery on my Micra was disconnected, and really missing my radio! Does anyone have the code? Number is BP334947256275. Help much appreciated. Many thanks. Refine the instructions for removing the radio and locating the serial number: Carefully remove the radio from the center of the console following these steps on how to remove the radio. Once the radio is out, locate the label attached to the box. Identify the 14-digit serial number situated below the barcode on the label. Hello, The battery recently went flat on my 2006 Nissan Micra. I have removed the radio to get the serial number: Blaupunkt-Werke-GMBH. BP5387 6 9679245. To get the code for the Nissan radio made by Daewoo, you need to locate the Serial number, Part number and Production Date. You can display this info on the screen by locking the radio for 60 minutes. For it, enter the code 1111 three times. You can also find this info on the label attached to the unit box, made visible by extracting the radio. lyglAlu.
