Depends what format your sat nav is programmed to accept (decimal/d

ss/d

sss) as it makes a VAST difference !
I've found that dropping the final digit on some coordinates is fine..... Also the ACSI and the All the Aires books use different sat nav formats.
The apps are good, both camper contact and park 4 night and the ASCI app allow the option to navigate via the APP.
We generally run a sat nav and the iPad with the APP's which works well.
We go over next week too, Rosslare/Cherbourg and then south to the Med via the west coast.

Not sure on you garmin system.
But two popular guides camperstop Europe and all the Aires express sat nav coordinates in different ways.
And on tom Tom when you start to enter coordinates it gives examples of how to in put them. You must follow the exact format.
For example n47 26 42 w2 27 2
I would in put N47.2642 and W2.272 if you require more digits but 0 at the end not before any numbers as 02 would be a different location to 20000000
Dots and comas can be important.
If it helps try in putting an Ireland one and see if it takes you to the right place
Try N52.7354237 w9.534030 the west could also be entered at -9.534030 if either of those take you to Doonbeg you have got it right.
When you do a French set of coordinates check the destination map is where you expect it to be.

In settings you can change the format to what ever suites you,

I had one and was able to change with ease

And for those who need to convert and practice your arithmetic

If your position is in decimal degrees (e.g. 51.50184) and you need degrees, minutes and seconds then...

The whole number before the decimal point, 51 in this case, is the degrees.

Take the decimal fraction of the position and multiply by 60...
0.50184 × 60 = 30.1104
The whole number, 30, is the seconds.

Again, take the decimal fraction of your new number and multiply by 60...
0.1104 × 60 = 6.624
This is the seconds.

So 51.50184 is the same as 51° 30' 06.624"

Working the other way (using the same position as above)...

Divide the seconds by 60...
6.624 ÷ 60 = 0.1104

Add the minutes and again divide the total by 60...
0.1104 + 30 = 30.1104
30.1104 ÷ 60 = 0.50184

Add the degrees to get the final answer...
0.50184 + 51 = 51.50184

North and East are positive (+), South and West are negative (-).

There is actually 3 different formats that are widely used, there is more but not used on commercial satnav's:
Same coordinates below in the 3 formats....... confusing ain't it !

degrees minutes seconds: 40° 26′ 46″ N 79° 58′ 56″ W
degrees decimal minutes: 40° 26.767′ N 79° 58.933′ W
decimal degrees: 40.446° N 79.982° W

That is a good tool, but I was thinking more of how to display them on the device to use in sat navs etc.

Use www.latlong.net.

Zoom into the map, find the location you want to go to, tap the screen to create a point at the desired location. The data section of the screen then displays the coordinates
