How To Find Your Clarion Radio Serial Number
To locate your Clarion serial number you will need to remove the radio and locate the radio label which is located on the top or side of the radio casing. The serial begins with either CL, PP, or PN, then followed by a series of numbers. The first number of the last 7 digits in the serial number will be a 0. For example, 0003742.
There are online guides and video tutorials on YouTube that can help with the removal of the radio.
