In reply to ERU:
GPS will work anywhere on the globe, it needs to be set to the correct datum and position format to display your location in the correct format to interface with a map, these settings “should” be on every map.
note that if you have only ever used OSGB then you will want to spend an hour or so working with a normal map because northings are not normally straight lines. when you are nearer the poles this begins to matter.
also note that currently declination is POSITIVE 5o 9’ in that part of the world, very important if you only ever work in the UK.
then you just need the map or data. Can’t help there but I’m sure someone will be along to tell you where you can buy it.
