Hi everyone.

I changed the battery of my car (superb)  and now the radio ask for code and I don’t how to get it any one can help me here plz 

Welcome.  Someone can help hopefully.   I assumed not a factory fitted unit as the code should not have been lost.   Best you tell exactly what your car is and what radio. 

Could it be written on the headhunit as I agree with the above?

It’s Skoda superb , factory fitted  

i disconnect from the car and   Connected back but now needs the code 

the serial no is   SKZIZ319880444

if some could know about it 

Have you looked on eBay for someone offering a decoding service?

It should come back by itself if you leave it a while. It will have been coded to the vehicle at the factory, but it might take a little time for the car to recognise it again.
