CO-ORDINATES?

[Wedders_Gasman]

Can anybody give me a quick lesson in navigation, or tell me where to research it.
I can't seem to grasp what to set my 2720 to for long. & lat. British Grid etc. etc. and then how to transpose all the different figures you come across for locations in minutes and seconds and things.
I am travelling to France in 2 weeks and want to locate certain places by GPS location.

Please help.

and want to locate certain places by GPS location

Try typing in the address
Seriously, if you can locate a position on a map, why not do the same on the GPS. You can zoom in, & use the touch screen to 'point' to a location. Then, off you go.

What different formats can the 2720 accept?

The 2610 format is h ddd mm.mmm and this is the only format it can accept. If I have the co-ords in a different format then I have to use Mapsource in the appropriate "coords mode" to convert that to something the 2610 will understand.

At starting point for research might be http://en.wikipedia.org/wiki/WGS_84 ?

Thanks for the interest, I am probably not making myself clear. I can navigate routes, add favourites etc. I can't cope with the numerical navigation part.
For example I wish to find a campsite in France with the coordinates:- Long. 0 00 07,13 Lat. 47 14 48,52 How do I do it?
Thanks

The format of that looks a little odd to me - I'm assuming this "converts" to
N47 14 48.5 W0 00 07.1 - somewhere near Samur ?

If so, then I'm not sure about the 2720 but for the 2610 you wouldn't be able to enter a Waypoint directly in that format. Using Mapsource I'd select Edit/Preferences/Position and choose Lat/Lon hddd mm'ss.s'' format, then create a Waypoint (anywhere) and set it's properties to be N47 14 48.5 W0 00 07.1

If I didn't have Mapsource then I'd use this site
to convert to h ddd mm.mmm' format
i.e. Degrees, Decimal Minutes: 0, 0.1183 -47, 14.8083

and enter that into the 2610 (but with only 3 decimal places)
i.e. N47 14.808 W0 00.118

I haven't got my 2610 to hand but, if you enter a position by 'pointing' at the touchscreen, it should come up with a lat/long. As others have said, there are better ways to do this by using a PC, with or without Mapsource.

In Mapsource, Ctrl - T, enter Lat/Long (use decimal seconds rather than your seconds with a decimal point) & press enter. The map 'centers' to your co-orinates. Add a waypoint flag, name it, and you've done it.

Thanks for that, BUT, how do you know what is N or S or E or W for your Lat. and Long. if it does not specify?
Thanks

Thanks

If you're referring to a place that is north of the Equator, then the Latitude will start N. That's most places that you're likely to ride or drive to!

E or W refers to East or West of the 0° line of Longditude - the Greenwich Meridian.

But I can't figure why you need to be doing this unless the ONLY data you have is the Latitude and Longditude.

Thanks

If it does not specify it's not really a good format

You might see -ve values for West and +ve values for East

Take a look at http://en.wikipedia.org/wiki/Longitude and http://en.wikipedia.org/wiki/Latitude

I have all sorts of numbers knocking around in all forms. I have a motorhome and I tow a trailer with my 1200gs on. Various sources supply campsite locations in different GPS formats and also I believe POI's. I am going to France in a couple of weeks and want to clear up my navigation problems before I go.
