The documentation for the car says the radio ought to be
28185 9U10A / PN-3001P serial number 0022606 pin code 2375.
But this pin code doesn't work.
Upon removing the radio it has numbers: 28185 9020A serial number PN-3000PA 0011825 and in the chassis of the radio has these numbers marked: CL081870011825
Your radio is made by CLARION and the only CLARION code available for free (using a serial number ) from anywhere on the Internet is if your radio also has a BARCODE SERIAL NUMBER beginning with C7000000 + + + + on a label somewhere on the metal casing.
If not then it will only be available from your Main Dealer or a Decoding Service or your local Car Radio / Audio Store who will connect a laptop to read/recode the memory chip (EEPROM)
