WGS 84 Waypoints

Capt. Paul: I am just now getting to know my Garmin 541s and learn about navigation, attempting to manually load some waypoints you had in the last edition of La. Sportsman. The unit is set for WGS 84 and the waypoints you provided were in that format, but the unit does not allow the decimal between the minutes and thousandths of minutes. Exposing my lack of knowledge, but does this matter and how do you manually enter these in this format? Thx for any advice.
Wrong Position Format?
~ Captain Paul's response to: ~ Wild Bill ~

Two of the least understood terms in the GPS settings are DATUM and the Position Format.

You seem to have the DATUM correct using the WGS 84 settings, but I suspect that Position Format or “Location” settings are not the same.

In latitude~ longitude settings, you usually have the choice of Decimal degrees, ie. 89.1234567° (DDD.ddddddd), Degrees, minutes and tenths of seconds, ie. DDD,MM,SS.s (89°20’ 15.8”) and Degrees, minutes and thousandths of minutes, ie. DDD, MM.mmm (89°20.123).
By your description, it seems that you are trying to enter one of these position formats into another format.

To correct the procedure, you will have to mathematically convert one to another, OR simply change the GPS Position Format setting to match the one you have.

Try this out and get back with me.

Unless otherwise specified, all positions are stated as Degrees, minutes and thousandths of minutes (DDD,MM.mmm) and were determined using WGS 84 Datum. All bearings and courses are stated in Magnetic degrees.
