For UK users of Garmin SatNav / GPS systems it’s well worth knowing how to use British National Grid references. Just follow the instructions below, it may look a little complicated but once you’ve done this a few times it becomes very easy!
To get you started we will create a waypoint for Castlerigg Stone Circle, Cumbria.
National Grid Reference: NY291236
Open the Garmin mapping software, MapSource.
From the main menu select Edit and then Preferences (or Ctrl+Shift+P) click the ‘Position’ tab and select ‘British National Grid’ > OK
Create a new Waypoint
NB: The map screen doesn’t need to be showing the area where the new Waypoint will be located. Click anywhere on the map page with the Waypoint tool selected.
…a new waypoint properties window will open.
Enter the details below (as in the image above). The National Grid reference for Castlerigg Stone Circle is NY291236:
Name field – type in a description for the Waypint or leave it as a number.
Symbol field – choose a symbol from the drop down menu to suit your new Waypoint.
Position field – enter the National Grid reference as follows noting the format:
NY 29100 23600
NB: Ordnance Survey map (OS map) grid references are given as 6 figure ‘coordinates’ as the system was originally designed for use on paper maps and so the level of accuracy was limited. GPS / Satellite Navigation systems however work to a much greater degree of accuracy hence the 10 figure ‘coordinates’. MapSource requires that the three elements of the coordinates are seperated by a space.
Uncheck the ‘Unknown’ check boxes and complete the 4th through 6th fields if you happen to have that data!!
Comment field – enter any useful information or leave blank.
Display field – choose an option that suits you
Categories field – select an appropriate Waypoint Category
NB: you’ll see from the image above that I’m yet to create any Waypoint Categories! Best to have created an appropriate Category prior to the above step:
To create a waypoint category:
1. Select Preferences from the Edit menu. The Preferences window appears.
2. Click the Waypoint Categories tab.
3. Select the text in a Category field, then enter the Waypoint Category name (i.e. “Campsites,” “Rest Stops,” etc.).
4. Repeat Step 3 as needed.
5. Click OK. Your Waypoint Categories are saved.
Finally, click the ‘Show On Map’ button and the map will zoom to the waypoint and centre on it. Click ‘OK’ and you’re done!
The new Waypoint is displayed on the map and is also shown on the Waypoint tab of the User Data Tabs area of the MapSource window ready to save or upload to your GPS.
