What is the process to reset my clarion pu9983b

We don't have access to radio codes because they are secure information. You will need the serial number off the paper tag on the radio and the VIN of the vehicle, then either see the local dealer or go to radio-codes.com. Some radio's will display the serial number of the radio by using a special sequence of controls on the radio. radio-codes.com will instruct you on how to do this if your car has the ability. There is a charge for this information.

3345 try this cannot guarantee it will work as i dont have the make and iam assuming its a clarion so i have used the clarion de encryption from the l?ast 4 numbers

have you tried calling a dealership????

honestly, peugeot charge about 5 quid to recode it. i had to do it on my own car and it took less than 10 mins and i am sure it was like £5.49 or something as ridiculous.

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)

ebay sells the unlock cd, less than a fiver and emailed in minutes, u can unlock any 1s radio for a fiver then.

The radio will have to be removed from the car dashboard
.Then please quote the MAKE + MODEL of your radio plus ALL the LETTERS and NUMBERS on any LABELS , BARCODES or STAMPED IN THE METAL CASING.
Also quote the MAKE of CAR it is fitted into.
Please note: Not all stereo codes can be calculated from the Serial Number
