If and when I get sent the Map Coordinates can I just enter them
on the gps (SP111) or can I find them via my mapsource on p.c or is the answer both

and if so how and where do I look/enter them


heres one N53.71088 W1.77439


thanks in advance

On your pc enter a waypoint anywhere, then click on the waypoints tab on lhs. Right click the waypoint you have just entered, select properties. Edit the coordinates to your values, click on show on map.

The position you gave is latitude and longitude in degrees and decimal degress (ddd.ddddd)

Sometimes lat/long is expressed as degrees, minutes and decimal minutes (ddd mm.mmm). This is most common.

It can also be expressed as degrees, minutes and seconds (ddd mm ss.s)

Your unit needs to be set for the relevant format.

Firstly, you need the Lat/Long in the following format.

N51 52.078 W001 29.910

To enter it directly into the GPS.

Press and hold the ENTER key, this will bring up a display
Waypoint Marked, which will be a new wayppoint of your present location, You can then edit the information in the display, once you have finished entering data press the ENTER key to finish then the QUIT key, it will be saved to your waypoints list.

Using your PC, open the Mapsource, Click Edit, New Waypoint.

Hope I have explained that ok.

Unless someone knows a better way.

no its just a ford that I found in my travels I just used the Coordinates as an example

thansk for the info it helped ta

Or in Mapsource you can:
on the top menu bar - View/Go To Position
or press CTRL+T
and enter the coordinates.

Terry:

There is one more issue that you may or may not need to consider, whether you need to worry about it depends on two factors:

1) What country you want to define the waypoint in, and;
2) What precision you need from the waypoint you are making.

The issue is that of map datum. All the Garmin automotive GPSR's use WGS 84 (World Geodetic Survey 1984) as the datum for latitude and longitude. If the paper map you are transferring the waypoint from also uses WGS 84 as the datum, then the result should be an exact match.

If the paper map uses a different datum, then there may be a slight difference between the location of the waypoint as shown on the paper map (in whatever datum it uses), and as shown on the GPSR, using WGS 84. For automotive navigation purposes, where an accuracy of plus or minus 50 feet is generally good enough, you can usually disregard differences between the paper map datum and the (fixed) WGS 84 datum of the automotive GPSR. But if you need great precision - for example, you are trying to locate a sunken ship using a marine chart - then you need to be aware of what the datum is on the paper map, and make the appropriate conversions.

The Garmin marine and aviation GPSR's, including models that address marine and automotive (e.g. the 276C) or aviation and automotive (e.g. the 295) give you the ability to choose the map datum you want to use on the GPSR. The automotive only models - SP III, SP 26xx, etc. - use WGS 84 only. This makes sense, because the electronic cartography used in the automotive models is all based on WGS 84, and differences between WGS 84 and local datums in areas that the electronic cartography covers (North America, Western Europe, SA, Oz) are pretty small. Also, automotive users really don't need extreme precision.

If, though, you plan to bury a bottle of expensive Scotch somewhere for retrieval later, and plot the co-ordinates from a paper map, make sure you are either using the same datums on both paper and GPSR, or do the datum conversion, otherwise, you might need to bring along an earthmover to find the bottle later on.
