Hi I have a customers 306 and when we disconnected battery lost radio code. There is one in the manual which I have entered but it doesn't wrk. Please help!!!
Your radio is made by CLARION and the only CLARION code that can be calculated (using a serial number ) anywhere on the Internet is if your radio also has a BARCODE SERIAL NUMBER beginning with C 7000000 + + + + on a separate label somewhere on the metal casing. (Note ...not beginning with CL.)
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) inside your radio.
Sorry....your code will only be available from someone with access to the Main Dealer database or the unit will have to be taken into a Radio Decoding Service
It is unlikely to be available for free from anywhere on the Internet
