I have a 2009 Hyundai Tucson limited with intermittent radio problems. Sometimes the radio will just shut off, no display, nothing like it has no power with different time periods. In other words sometime 20 mins maybe 30 and sometimes it will last all day. Sometimes the volume will just cut back to where I have to turn the volume up all the way just hear it. Again no specific time amounts. No nav system just the single cd, am fm radio. I checked the inputs at the amp and they seem to be tight and wiring looks good. Any ideas? Thanks
