[C320-list] GPS malfunction

[Dave Hupe]

 I have an older Garmin unit that took nearly 15 minutes to initialize and lock onto satellites.  It turned out there was a pretty inexpensive internal battery that needed to be replaced. It looked like a garage door opener battery but gets soldered in. An electronics friend replaced it forme.  Don't know if you may have a similar issue with your Raymarine unit.

 Hi all,

I have a C-series Raymarine MFD. I went out the other day and the GPS was not fixing. 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!
