NOTE: This information is dated. Similar steps are likely used to enter lat/long values newer Garmin Drive Smart units.
Trails in rural areas occasionally cross, or reach, back country roads where there may not be a functional address. That is, there is no urban-like address that has a house number, street name and so on. If you are given the latitude and longitude of that rural location, you can enter the latitude and longitude in most in-car GPS Receivers (e.g. Garmin Nüvi GPS Receiver or the newer versions like the Garmin Drive Smart 60 LMT6).
I am assuming you have prior knowledge of latitude/longitude coordinates. If not, and you need to learn or review what they are, visit the Lat/Long Coordinates Explained page.
The Bruce Trail crosses the 21st Sideroad [Blue Mountains Map 24, Ed 28.0] in the Beaver Valley section at approximately 44.511710, -80.380860. Also, there is a recommended parking location at approximately 44.513039, -80.374948. These two sets of coordinates were determined from using the satellite view in Google Maps. The way to acquire the lat/long is to zoom in on the location (e.g. parking spot) and right click that spot in Google Maps and select "What's here?" from the menu that pops up. Check the bottom centre of the monitor screen and you will see another form and in it are the lat/long coordinates. Click the coordinates. The whole Google Maps screen will change. At the top, left you will see the coordinates. Copy the coordinates and paste them into any documentation where you may need them. In this case, you have acquired the coordinates yourself instead of someone giving them to you. So, if you want others to have those coordinates you can paste them into a Word file or an email.
Entering Coordinates in Newer Garmin GPS Receivers
Entering Coordinates in a Garmin Nüvi GPS Receiver
STEP 1: Select "Where to?"
STEP 2: Screen content may vary depending on settings.
If "Coordinates" does not appear on screen, select the down arrow (lower right).
STEP 3: Select "Coordinates".
STEP 4: Select the format you need. In this example, decimal-degrees has been selected.
Note: If you acquire the coordinates (latitude and longitude) of a destination from sources such as Google Maps or Google Earth, one may alter settings in Google Earth to provide coordinates in the degree, degree/minute and degree/minute/second formats.
STEP 5: Enter Coordinates and select "Next".
