POI Location is off

 

I loaded up a few POI's from my local area. I got the cordinates off of google earth. I loaded them onto the GPS, but they are about 15 miles off. I triple checked the numbers and they are correct from what i got off of google. Unit is a Nuvi660. Any input ? ..Thanks

Formats

There are several different formats that coordinates are expressed in. Three commonly used formats are DMS (degrees, minutes, seconds), Decimal Degrees, and GPS coordinates.

Now I don't know that the problem is format, but I think you should check to make sure you are using the same type for each application.

The following calculators will convert Lat / Long coordinates between three commonly used units types. If you have the coordinates in one unit type and desire to know them in another then use the calculator for your known unit.
The three unit types are shown below with an example of how a map point would be expressed.

Lets look into it

Gives us the address you are trying to plot (number, street name,city,state and zip), lets us look the coordinates and then see if there is an improvement, I'll try on Mapsource

Mismatched formats

As Jim1348 said, there are several formats for displaying coordinates - it's highly likley that your Nüvi and Google Earth are not currently using the same ones.

See this post: arrow http://www.poi-factory.com/node/6316

for someone who had the same problem. The safest bet is to use files, to transfer this kind of information between devices and programs, rather than "Eyeballs and Fingers" smile

Coordinates

This is the Address..

Its a WaWa, at 305 Market Square Drive in Prince Frederick Maryland 20678. I am also trying to load a Kawasaki Dealer in Huntingtown Maryland, but it is being built and doesnt have a street address yet, so i used the mapping to locate where it is.

When I look it up on Mapsource, it doesn't show up. Using gpsvisualizer, it says that address is at:

38.535389 -76.586707

When I put those coordinates back into Mapsource, it shows it to be approx. at 1855 Constitution Ave.

is the Format. I will have to play with it and see what i can find. Thanks to all

Google uses "Decimal

Google uses "Decimal Degrees" (ddd.dddddd) while most GPS units ship using the "Degrees, Minutes, Seconds" setting.

I don't have my nuvi 200 with me, but I seem to recall if you select "Where To?", and scroll down and select "Coordinates", there's a button there that allows you to change the format for your unit.

Yes...

... I changed the format on my 260 to decimal, just because it's easier to enter that way. I use it to force the GPSr to use the route I want, or certain roads I want, when it tries to choose a different route. I find the coords on Google Earth on the road I want past the last intersection where it can send me the wrong way. Then I create a waypoint in my favorites and use it a destination or as a via point.
