This is an unspecified radio in an unspecified car ? - you need to measure the voltage - if there's 12v at the fuse then there's probably a problem with the radio - If there's not 12v at the fuse then there's a problem with the 12v - follow the wire and see where it goes.

Good Luck..., August 2015
