My radio in 2008 ford focus stopped working .The word "LINE" is lit next to time

Hello, sounds like a setting on the audio unit. "LINE" is one of the inputs -- you can plug in an external device to play through the radio. Use the owners manual to learn how to properly control your audio unit. If you don't have one, download one online -- https://usermanual.wiki/Ford/Ford2008FocusOwnersManual762316.1895440728
