+lancs-sue Posted June 2, 2023 Share Posted June 2, 2023 Could someone please tell me the correct position on a Garmin 64sx. I find the last part of the co ordinates is now 4 digits and I am sure there only used to be 3 digits at the end. My GPS is set to hddd mm.mmmm, map datum is Ord Srvy GB and Map Spheroid is Airy. Thank you Quote Link to comment
+MartyBartfast Posted June 2, 2023 Share Posted June 2, 2023 hddd mm.mmmm is correct, set the datum to WGS84 and ignore the last bit of the decimal. 1 Quote Link to comment
+lancs-sue Posted June 2, 2023 Author Share Posted June 2, 2023 Thank you. I have changed the datum to WGS84 and the spheroid has also changed to WGS84. Has the system changed in the last few years? Do you add a 0 to the end or just enter 3 digits? Quote Link to comment
+Viajero Perdido Posted June 2, 2023 Share Posted June 2, 2023 (edited) Mathematically, having a 0 at the end makes no difference. 12.345 = 12.3450. You can leave off the zero unless the Garmin insists. Note that any waypoints you manually keyed in before you switched to WGS84 will be incorrect (unless the earlier datum is effectively identical to WGS84, dunno); you'll need to re-enter them. But waypoints that you recorded ("mark") or electronically transferred into your unit should be fine. Edited June 2, 2023 by Viajero Perdido Clarity Quote Link to comment
