Why did you take the radio out to put into another car?

What radio did you take out, what car did you then put it into.

The radios in fiats do not have normal power connections like an aftermarket radio They have power then they take a digital signal from the car's can bus system telling them when to turn on and off.

If you play about and connect power to these digital lines or connect a normal radio to the digital lines in the car you can cause damage to the radio or the car.

Without knowing what you have done its hard to say what is really going on but its likely you may have damaged the radio's circuits that receive the digital information telling it to turn on and off
