my radio will not stay on it shuts of 7 second after i turn it on?

If you loose ur preset stations, it may be a loose connection on red wire at the radio or loose fuse socket. If you do not loose ur presets, then it may be a loose connection on the yellow wire at radio. If you do not loose ur preset stations and don't find any loose connections, check for 12 volts at the yellow and red wires with ignition switch on, if voltage is present and radio turns off, replace radio

what if I get a "no fuse" message in my dashboard and I loose all the preset and my remote key doesn't work
