Question about Garmin GPSMAP 76 GPS Receiver

1 Answer

Apparent Datum shift but still selected to same datum.

While setting up a charting program noticed the position indicated on the chart was about 1/2 mile off although the lat/long readings correlated to another GPS which displayed correct position on the chart as read on a computer.  The waypoints also are now plotted off of position by the same anount.  The datum selected did not shift as it is WGS84.  Another sailor said he had the same problem at one time and had to replace the GPS.  What gives?

If your software is less than v4.00 then download this update:

GPSMAP 76 Ver. 4.00 as of Nov 29, 2006

If that doesn't work it may be necessary to do a master reset.

How do I get traffic subscriptioin code


For garmin traffic receivers there is no code needed, as long as you are plugged into a working 12v power source you should be getting traffic updates. If you are not noticing any datum you may be in an area that is not covered for traffic updates.

Hope this helps!

I have a garmin gps72 but now i have move to other country first i was in india and now i am in saudi arabia when i put the coordinates its showing in many kilometers

You need to find what Map Datum your map is using, it should be printed in the margin or the title of the map. Then you need to set the Map Datum the same value in the GPS 72 (Main menu, Location Tab). Most modern maps and charts use WGS84 but I wouldn't know for Saudi Arabia.

We are trying to set up our Navigation options correctly on our Triton 500. How should we have them set up? We are in the USA, Idaho.

In the USA you would set: Lat/Long as Deg.min.sec or UTM .. Compass at True North and Datum at WGS84. This assumes that your maps were constructed at datum WGS84 which is current standard.

My map on my garmine 60csx doesnt line up with the actual locations

The most common cause of consistent offset is DATUM selection. The DATUM was likely set to WGS84 at the time of recording then viewed later in NAD27, or vice versa. uses WGS84. The USGS generally uses NAD27

Also see this Garmin page. The DATUM is set under Settings | System if I recall correctly.

The unit appears to be inaccurate. While driving I am 50 to 100 yards past an intersection before the icon on the screen shows I have reached the intersection. I have updated the software and even did a...

1) change output pinning. This is an averaging method used for slow speeds. Disable / Enable as applicable.
2) change your datum. Typically, one would use WGS84. Other older yet popular datums include NAD27 and NAD 83.

You shouldn't have to connect to a computer. I don't have an OS map in front of me but I'm guessing they use UTM with a WGS 84 datum (if the map was produced after 1984 that is). Got to the Setup page then select Units. Change Position Frmt to UTM/UPS and Map Datum to WGS 84.
