There was no message saying that the unit could not find a fix/satellites, there was just no data being received. Can anyone give me an idea of where to start troubleshooting this? I'm not sure whether the  MFD has a built in GPS module or whether the module is external and linked via NMEA? I checked the C320.org site and someone mentioned that there is a GPS reset menu. I have not tried this yet but will do so next week. The boat was detailed just before this happened. I'm not sure whether that has anything to do with the problem. She looks great, but I'd rather have the GPS!
