How to Add Topographic Maps to a Garmin 62 GPS
More map detail can make the difference between ascending a mountain via a steep cliff or a more gentle slope.
How to Install Topographic Maps
Using a GPS without installing topographic maps is like navigating inside a game of Pong: all you see is a prosaic dot cavorting around the screen. Though the Garmin GPSmap 62 is a professional-grade global positioning system, not all models come preloaded with detailed maps. In this tutorial you'll learn how to easily install topo maps into your unit in just a few minutes.
The standard worldwide basemap that come equipped on models like the 62S may be fine for some folks that use their GPS sparingly, however, it only shows roads and major bodies of water. This is fine if you are trying to find Lake Ontario, but troublesome while hiking a remote trail.
The Garmin 62 has the ability to display detailed topographic maps scaled at 1:24,000. So what does that mean? In that scale, one inch on the map equals twenty-four thousand inches in real life. For those of you like me that fail to grasp measurement conversions, twenty-four thousand inches equals two-thousand feet. Like all topographic maps, elevation is represented through contour lines. Learn to read the contour lines and your wilderness treks will be much easier.
Advantages and Disadvantages of Topo 24K on SD
Though outstanding navigation programs like Terrain Navigator are on the market, most users wishing to install maps will gravitate toward Garmin's TOPO U.S. 24K. It is a cost-effective and easy to use program that is available in a DVD and SD card version.
If you are contemplating the pros and cons of an SD card installation versus a DVD install, I have come up with a few points that may help you make your decision.
- Installing maps from the SD card requires no computer and no computer software installation.
- The SD card maps are the quickest and easiest way to install maps on a GPS.
- The SD card is less expensive than the DVD.
- There is a chance that you could accidentally overwrite your SD card. Once you do, there is no way to retrieve that data.
- If you have multiple GPS units, you'll need an SD card for every device; this could get expensive.
- The TOPO 24K DVD has a larger coverage area. For example fourteen states are covered by the DVD for the Northeast, whereas nine states are covered by the SD card.
STEP ONE: Prepare the SD Card
Begin by removing the micro SD card from the SD card adapter. Generally, this can be done by gently tugging at the lip of the micro SD with a fingernail.
Though you won't use the adapter with this type of install, hold onto it as they are handy to have around the house. You paid for it after all.
Step Two: Prepare the GPS
Though the technologically proficient amongst you probably know this, one of your first steps should be to power down your GPS. After turning your unit off, remove the battery cover and batteries.
Make sure you set these aside as you'll need them later.
Step Three: Locate the Metal Slider
On the inside of the battery compartment, you'll notice a small metal bracket: this is the slider that holds the SD card in place. Slide this bracket to the open position by moving it toward the antenna. If you ever forget which way this widget is designed to move, the words "OPEN" and "LOCK" are printed on the unit, just millimeters way.
Once you've reached the open position, gently swivel this sliding bracket upward. You will most likely have to use a fingernail to pry this up. I personally wouldn't use any tools to move this slider, just let your nails grow another day or two if you can't quite get it.
Step Four: Install SD Card
Install the SD card gently, by placing it into the bracket. The words on the map card should be facing upward with the narrower end facing the antenna. There is a small white dimple in the GPS that will fit into a notch in the card's bottom edge. Use this notch as a guide before proceeding to the next step as it will alleviate any CRUNCH sounds.
Step five: Move Slider and Install Batteries
After the card is in place, pivot the slide downward and move it into the "locked" position. The locked position is toward the base of the unit away from the antenna. If you start to hear a crunching sound, you are probably doing this wrong. Turn your Garmin upside down and shake it to ensure that the card is firmly in place.
Remember those batteries I told you to hold on to? Now is the time to reinstall them and secure the battery compartment lid onto your system.
Step Six: Turn on Unit and Check Map Install
When I booted my Garmin up after physically installing the SD card, it automatically defaulted to the 24K series of maps without changing any settings.
As electronics are fickle, here are the instructions for selecting the new set of maps just in case your unit decides not to cooperate.
- Go to "Main Menu."
- Click on "Set Up."
- Click on "Map."
- Page down to "Map Information - Select Map" and click on it.
- Ensure that the map set you want, most likely TOPO U.S. 24K, is "enabled."
