    Trying to figure out which format to use and how to enter a negative number - example from B&B listings in Ireland:

    53.368400 -6.269650

    Thanks!

    Ok, those are decimal lat/long numbers and you don't say which GPS you're trying to enter them into. It varies from device to device so maybe you can tell us what you have?

    Oops, sorry, I have a 1490T

    Then it's simple, tap Where To>Coordinates>Format, and select the top format, then enter your coordinates (ignore the -).

    Thanks! There are no NSEW directions indicated in the listings, is there some way to tell which directions apply?

    Well if you're in Ireland it'll be N and W :roll: :wink:

    Cool. For us geographically challenged folks, what determines these directions?

    The equator would determine N and S.

    Greenwich England for E and W

    Coordinates are usually given latitude first then longitude. Positive latitude is North, negative is South. And then positive longitude is East and negative longitude is West. For us folks in the Americas, longitude will allways be negative. For you guys in Western Europe it will depend on where you are relative to the Greenwich Meridian.

    With respect to East and West problem. Is it possible to enter them all as positive using a range o 0 to 360 instead of the usual range 0f 180 to -180?

    I know that this is not a useful question, I am just interested in what is possible?

    Well most things are possible 😃

    You could enter it that way but no one would understand you as convention dictates that longitude is measured from a line that runs through the Royal Observatory at Greenwich, with the range running from 0 to 180E and 180W, with 180W and 180E being the same line.
