Nissan Blaupunkt unlock please

[boris_ford]

My Nissan Vannette Cargo battery failed, so I have had to reset everything.
no success with radio though.
Using the code on the tag has not worked.
The Radio is
Blaupunkt
serial = BP6340X5843058

part no = 7 646 340 318

any help will be greatly appreciated,

thanks, Boris Ford

hi, please provide me with Vauxhall astra 1998 radio code for blaupunkt 300 car radio RDS EON with s/n and model

7 645 852 520
GM 0300 T548 6564
90 532 620
fd670

Furthermore, please tell me how to input it. I seem to have tried several times with all sorts of instructions. I have been able to reset several times by holding 'AS' while switching it on. When I do it now it just shows '6 safe' and will not give ---- anymore. I just bought the keys to remove the radio and locate the s/n and model.

Many thanks
