Using A GPS with a Paper Map of the Southern Upland Way
Q. I'm from the US and plan to hike the Southern Upland Way in April/May. I have the maps from Roger Smiths guide. After some research I think I understand the reference grid to find locations on the map. My question is how to set my GPS to display these coordinates or even if is possible to do. I have a Garmin Fortrex 301. This device is simple and can display locations, waypoints, speed and such but it does not display topographic maps. What position format and map datum should I set into the GPS to display the ordnance survey grid for location?

A. Not sure which maps your guide uses but to set your GPS to display UK Ordnance Survey Grid References you should set it to Position Format = British Grid and Map Datum = ord srvy GB
Full details on how to do this on a Garmin Fortrex 301 will be in the manual (try the 'Set Up' screen).
Hope this helps . . .
A. In case you don't have a manual:- After turning on the Foretrex 301, press the Page button 3 times to get to the options page. Select Setup, then select Units. Then, as Mike says, set Position Format = BRITISH, Map Datum = Ord Srvy GB.
