Dear YourOldNemisis,

Thank you for the response.

Your boat heading is different to your COG. The heading data will come from your fluxgate compass and the COG comes from your GPS antenna. Usually heading and COG vectors appear starting at the bow of the vessel when underway.

Look at the vectors you have from the stern of your vessel the COG is the blue line and the purple is a tidal vector that appears when the system lacks data to calculate the tidal vector.

The COG vector coming from your stern and the tidal vector are all indicating an issue with your GPS data. Try turning on your heading vector and see how this relates to the COG vector.

I recommend a power on reset to the unit, before commencing this you will need to back up all settings and data as all of this will be deleted (including waypoints and routes).

Power the unit down from the breaker> power the unit back on> swipe the power on button from right to left as the unit powers up 5 times (just keep swiping in case you miss one)> the standby LED will turn purple and a small menu will appear> following the instructions select erase and reset the unit

Once this is completed you will need to complete the boat wizard for your vessel.

Have a look at the GPS signal in the homescreen>touch the Lat & Lon data>select satellites>what is the HDOP figure and how many satellites are there? -

Please send in a diagram of your system installation with all of the products, software revisions and how they are connected.

Many Thanks
Louise
