Clarion Radio Code

[Batem4n]

Hello all!


I need an unlock code for a Clarion PU-9971A, if someone could please assist! 🙂


Here are the serial numbers printed onto the unit:
899701899702


I know some people have previously said to read the “eeprom”, but have seen other users decode these without this being required - although I guess depends on the calculator and/or model of radio? If this is decodable without the “eeprom” being required, that would be fantastic. 🙂 Many thanks guys! 👍

Thanks for the quick reply. I’ll try this later when I’m back with the unit. Are the serial numbers printed on it (such as the one beginning with “CL” stamped on the side, not suitable for a radio code decode using Clarion-decoding software I take it? Thank you. :-)
