Hello, I have a fully loaded 2011 Galant ES/SE equipped with the MMCS integrated Nav, SAT radio, etc. My issue is I get a display with the word Audio flashing and what looks like an error code that states ; E DC. While it's doing that, I have no control over time, temp, navigation, CD or satellite radio. Don't know if it's the fuses or if the system is simply giving out. Any advice or suggestions is greatly appreciated.
