RADio with aux

[LC1]

I have recently fitted a pioneer radio into my ford fiesta flight (2002) snd seem to have no radio stations available it is just making the same noise that the normal radio makes without the code inputed so i am thinking is there a way i need/can put in a code or is it something else. 

Thanks

Have you tried the obvious and checked the aerial is connected properly?
Also some aftermarket head units will require an aerial adapter

What he said check the aerial, hope you didnt swop out your radio before making sure you had reception.
