I have a holden astra with a plaupunkt 520 bp 8391 2 4746127 what is the radio code please

if cam with car new, only car dealer can
if was added later, only blaupunkt can
by law in most countries, this is true.

google finds this in 1 second flat.
when car was new, with coded radio head end.
it has card in the glove box ,says dont lose this card and code
and put in a safe place it states.
the users guide (lost too) says to replace the battery the car
ask the radio its code first (or OOPS its locked out)(shows how it does)

Hi Kevin search through all your paper work, any repair order sheets from dealers hand books etc. If no joy you will have to go to Holden's there are far too many codes used to be able to offer any specific one for your radio. The Dealer may be able to obtain the code on your behalf. There will probably be a charge. Good luck

You will need to go to a Holden dealer for the code if it is still in the data base.

30 dollars is cheap try to buy that radio for that ?

1.turn the ignition on to reds .
2.turn the radio on.
3.on the front panel of the radio you will see a button with the lettering asp hold it in until it beeps.
4.then for example if the 1st number of the radio code is 4 ,you will have to press no1 until the 4 appears ,next number use no.2 and so on.
5.once all the number are entered then hold the asp button again until it beeps .
you are now finished the process

you can download when you google it car code generator for that kind of radio..... but you need to know SN

or may be you have security card that came with that radio and code should be there

dealer item... sorry..

download blaupunkt radio code generator
BlaupunktCalculator1.0.exe
http://www.ziddu.com/download/590988...or1.0.exe.html
install the software in your computer
take out your radio and put the radio code starting with bp on to the software and it will show your code
plug the radio back in press as button untill code comes up and input your code using 1234 buttons on the radio and press and hold as button untill it turns on the radio

Does anyone have any tips for obtaining the radio security code in an Astra without having to fork out the $25 - $33 being quoted by all the Holden dealers i've contacted?,

Thanks
