Basic cr702 radio question...
Hi, I'm sure this will count as one of the more obvious questions asked, but I'm having trouble entering my radio code. I believe the radio is original to the car. I have the code from the dealer. The first two digits are zeros, which I dont have buttons for on the fascia. If I just use the four digits after the zeros that doesn't work, and I've tried 6666, which also doesn't work. What am I doing wrong?!

email Simon at FRF Swansea if it's the original radio and get the correct code.

Thanks - is that a different process to what my local dealer would have done then? I have the code confirmed from my dealer, which matches what the previous owner told me

Thinking back as I have had several CR-702's. I seem to recall that the maker didn't use any zero's in the radio code.
I have just looked in a CR 702 handbook and it only refers to the six digit key pad for code entry. Some codes were repeated try 4645. FRF don't usually answer emails these days and ask people to phone them. Mention you are a member of the Volvo Forum. Otherwise you will have to open up the head unit and read the diodes. I believe there is help here under FAQ's above, YouTube, and in the past there have been other threads on the subject. Bob. |

There is another method of determining the code , That is the Main volvo database which is separate , the dealer has to access this and they need the Radio serial number , the model type from the front panel ( CR 702 ) and the part number from the label on the back .. sometimes they need the front panel colour too , grey or black . I would be surprised if any of them there know about it , knowing how high the labour turnover rate is of the front counter staff . however the service IS available .. so press them for it ! you might find a later radio CR 906 for example, which is considerably better.

From your comments above, i'm guessing the code is "00666" and as there are no zeros to enter with the keypad, have you tried "666" on its own?
This may be of help : https://www.radio-code.co.uk/CR702-c...try-guide.html Gives the method for entering the code. They can also provide the correct code if other options fail. However, have you checked the fuses? There are two for the radio, one is for the switched accessory positon on the ignition barrel and the other is a permanent +12v feed for the memory. If that isn't present, the code entry won't be accepted and other things may not be working such as the clock, interior lights, hazard warning flashers and/or similar.

The CR-702 has to be a 4 figure code. The makers (Alpine?) favourite numbers were often a mixture of 4's 5's and 6's! Trouble is after 3 false entries, 'EEE' and then 'CODE' for another go, the radio then locks out further attempts for 1 hour!!

Useful info Bob! I've never had an OE Volvo head unit that needed a code, only had one OE Volvo head unit in my first 740GLE about 15 years ago. That was the previous model that didn't have a code option or if it did, i wasn't aware of it!

Tried that link Dave as it looked excellent and thought I would test it. The site needs you to input the '14 digit serial number'. Got my old CR-702 out of the garage for which I know the code, but unfortunately the serial number is only 11 digits, or an alternative 9 digits long. It won't accept a shorter number. Looking again at the site I see it seems to say it is only for HU's made by Phillips. Bob.
