Finding your Nissan radio serial on the radios label.
It is quite simple to remove your Nissan radio. You will need a set of radio release keys (PC5-83). These are inexpensive and are around £3, you can obtain them from Amazon.
Once you have the radio release keys, push them into the 4 holes in each corner of the radio (See image), apply a little pressure and the radio will release from the dashboard. The radios label will be located on the radio's casing.
Once the radio has been removed you will need to locate the radios label, which is on the top or side of the radios casing.
