Hi i need a code for a clarion cd player PU-2294A C70000003312 many thanks

go to dealer with vin or vehicle and proof of ownership

usually you can define error codes by entering the name of the item and error pu-2294a into google

google: clarion pu-2294a error code

When you disconnect your battery and then reconnect it again, it disables the radio. This is an anti-theft protection for your car radio.
The enable your radio the activation code is in your vehicle owner's manual. If you do not have this code you need to go to your vehicle manufacturer's service centre and get them to enter this code for you.

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 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

Call Clarion with the model numbers and they can give you unlock code.

If you have run out of 'lives' (too many wrog codes entered), I've read other people suggesting leaving the radio powered on for 1 hour to reset it, although I have not tried it myself so do not know whether this will work.
