When navigating and using coordinates the coordinates do not match my location or my destination on my map, I’m in the uk and using a Garmin tactix sapphire, can anyone help with this issue

    It could be your position format for the coordinates you are using are in a different format. For example, if you go outside and save a waypoint to where you are standing, you are going to see the position format for where you are standing, based on your default settings. If you navigate back to that saved waypoint, your watch will take you back to your home where you saved it.

    To change your position format, you will go to the System > Format > Pos. Format menu. It is likely the Format menu will need to changed to the proper origin format type for the coordinates you are adding to your watch to navigate to later.

    One example request that is common in the United States, when I speak with US Military members, they use both the default standard format in their watch but they also have to change their watch to use the "MGRS" format since the military uses that different system for a coordinate/waypoint.

    Make sure your GPS position format is set to British Grid, then your watch will display OS Grid references rather than lat/long and use the geoid that the OS maps are referenced against. I am assuming you are using OS Maps, either 1:25000 or 1:50000.

    On the map find a reference point such as a trig point, or contour line crossing a road or a boundary stone, etc etc. Using a compass roamer read off an accurate OS Grid ref and after setting one of your data fields to display the OS grid ref, go to that location and see how close the watch is when the GPS is running, usually +/- 10m or so.

    I have a F6x sapphire and I use the OS grid ref all the time to xref against a map while hiking and its just brilliant, especially in very low vis or at night.

    hope this helps
