entering co-ordinates into Garmin Nuvi

Post by woodiebro » 12 November 12 4:13 pm

Can someone please explain how I enter the co-ordinates into my new garmin nuvi, 2595
Some co-ordinate figures in map books end in 2 digits ( 38 04 17S 145 39 51E ) where as the nuvi setting ends in 3 digits.(ddd° mm.mmm' and ddd°mm' ss.s")
I cant really explain this well as I have always worked with marine GPS and used Digital degrees or ddd°mm.mmm'


I'm a bit GPS challenged in this one but I'm sure it simple.



Thanks

Terry

Hi. The above format would be degrees and digital minutes. Perfect for geocaching.
On the nuvi, go to Where To>Coordinates>Format> hddd mm.mmm' >OK. Then enter away.

Generally speaking, the nuvi is suited for in-car use.
Cheers.

If that doesn't make sense, what coords do you have?

There are 2 basic ways of giving the same coordinate.

Degrees-Minutes-Seconds 360 degrees in a circle, each degree is divided into 60 equal parts- called Minutes. Each Minute is divided into 60 equal parts- called seconds. Note that in your example- 38 04 17S 145 39 51E the last 2 pairs of number for the northings or eastings will never be greater than 59.

Degrees-Minutes-Decimal Minutes, same as above, but instead of 60 seconds in a minute, there are 100 equal parts- Decimal minutes.

For extreme accuracy, then the Decimal minutes or seconds can again be broken down into equal parts. In some circumstances, there can be 5 or more decimal places, however, we are now talking centimetres or millimetres of difference here, which is an accuracy GPS units available to the general public cannot measure.
