bejay Posted July 16, 2007 Share Posted July 16, 2007 Can anyone please tell me how to set up a Garmin Etrex to work on the grid system used on IGN 1:25000 maps. I don't seem to be able to match any of the grid systems stored in the unit with any of those described on the map.I am not in france at the moment so I can't test it out by trial and errorbj Link to comment Share on other sites More sharing options...
jc Posted July 16, 2007 Share Posted July 16, 2007 Can't tell you about that grid but if you can locate the place you want on the views on the geoportail.fr website,you will find at the bottom of the screen the latitude/longitude. Link to comment Share on other sites More sharing options...
bejay Posted July 17, 2007 Author Share Posted July 17, 2007 Thanks for that link jc.I think I have found the answer to my own question. I found a note on the edge of the map which indicates that the blue grid squares follow UTM-WGS84 protocol. That's good enough for me.We shall soon find out!bj Link to comment Share on other sites More sharing options...
Salty Sam Posted July 17, 2007 Share Posted July 17, 2007 BJ, I can confirm you've done it right, the "UTM - WGS84" protocol is the the correct configuraton. Link to comment Share on other sites More sharing options...
