UTM Position Format
Garmin has the UTM format on all of its handheld devices. The GPS does not receive a UTM signal. It simply converts the position it receives from the satellites to display it in the UTM format.
The UTM system is not a single map projection but a series of sixty, each covering 6-degree bands of longitude.
If the formatting of the coordinates does not match the format on the Garmin Device, confirm the format of the provided coordinates. Maps will often provide the map datum they use. To change the position format and map datum, refer to your owner's manual.
Coordinates from different sources may have fewer digits compared to what must be entered on the Garmin device. The numbers that are being used are meters, so when entering these types of coordinates, a zero can be added at the beginning of the coordinate set. Here is an example:
Coordinates for the Eiffel Tower, Paris, France:
Grid-zone Designation 31U
UTM Easting 448,265
UTM Northing 5,411,920
How these coordinates would look entered into a Garmin device:
Grid-zone Designation 31U
UTM Easting 0448265
UTM Northing 5411920
In the example, the UTM Easting digits line did not match the format. In order for the Garmin device to accept the coordinates a zero was added at the beginning; however, the Garmin device will still guide you to the Eiffel Tower. If the zero were entered at the end the Easting of 4482650 the location would be far off as it is 4,482,650 meters. Not the needed Easting of 448,265 meters, entered as 0448265.
Using the UTM format on a Garmin Outdoor Handheld
When entering coordinates on a Garmin device using the UTM position format you must first enter the grid-zone designation followed by the coordinates.
