Hello all,
someone can you help me?
I have the car radio locked...I do not have the pin...!?

Car Fiat 500
Car radio Blaupunkt Fiat 312 Black MP3 SB05
SN.: 7647389316 - BP738973795174

...among other things, I connected the house to be able to hold on, but after a while it turns off.
What's wrong?

Thanks in advance to all!!!
