Your Garmin nüvi 66LMT has limited storage space for waypoints. Once you reach that limit, your GPS can't hold any more data. Smart ExpertGPS users have figured out how to eke out every last bit of memory space on their Garmin GPS receivers. Before each outdoor adventure or visit to a project site, they use ExpertGPS to back up the contents of their GPS, and then clear the GPS data memory. They can then download as much data as possible onto their GPS (leaving some room for GPS data collection out in the field). When they get back, they use ExpertGPS to upload all of their Garmin waypoints onto their computer and save it. Once they've backed up the new data from their GPS, they can clear the memory again, keeping their GPS ready for their next trip.
Backup your nüvi 66LMT waypoints by using ExpertGPS to transfer them to your laptop or desktop computer. Now you've got a safe back-up of all of the important data on your nüvi 66LMT, and use ExpertGPS to find and create new waypoints to download to your Garmin GPS. Before you update your Garmin nüvi 66LMT firmware or install a custom basemap, Garmin recommends that you backup all of your GPS data. ExpertGPS gives you the peace-of-mind that your Garmin nüvi 66LMT data is always safe.
View your Garmin nüvi 66LMT waypoints over USGS topo maps and aerial photos. These are actual 1:24000 scale topographic maps from the US Geological Survey, giving you much more terrain detail than the maps that came with your Garmin.
Instantly switch between topo maps, aerial photos, and color urban imagery using the T, A, and U keys in ExpertGPS. This ability to toggle back-and-forth between several views of your GPS data is unique to ExpertGPS, and is one of its most popular features.
ExpertGPS comes preloaded with all the line patterns and cartographic styles you need to draw highways, railroad tracks, transmission lines, streams, and more. And the waypoint and track style editors let you create your own map symbols, change track colors, and customize exactly how your GPS and map data is drawn.
Why waste time entering new waypoints on the tiny screen of your Garmin nüvi 66LMT? ExpertGPS can do it 5x faster! Use the New Waypoint dialog in ExpertGPS to create new waypoints and POI listings for your Garmin GPS. As you type, ExpertGPS automatically suggests the best possible name for this waypoint on your GPS.
ExpertGPS lets you get the most out of the waypoints on your Garmin nüvi 66LMT by making it easy to assign the best symbol and to give each waypoint a long, meaningful name (using a real keyboard, not the little controls on your GPS). Think about it:
Your Garmin nüvi 66LMT can hold 1000 waypoints. Waypoints on the Garmin nüvi 66LMT can contain up to 60 characters. Waypoint comments (notes) can contain up to 255 characters. How long would it take you to enter all of those waypoints by hand into your GPS? ExpertGPS will save you hours on this one task alone!
ExpertGPS lets you link a photo to any waypoint or POI and includes a built-in photo viewer. And you can add your own detailed description to any waypoint - store as much information as you need.
GPS coordinates are easy to mis-type. Using the Waypoint Tool in ExpertGPS to create new waypoints reduces the chances of making a mistake when manually entering coordinates on your GPS. ExpertGPS takes care of all of the coordinate conversion and datum shifts when communicating with your Garmin nüvi 66LMT, further reducing errors.

ExpertGPS converts addresses to GPS coordinates with its built-in address geocoder. Enter any address in the US (or in several dozen other countries) and ExpertGPS will bring up a map of that location and create a GPS waypoint you can send to your Garmin nüvi 66LMT.
The Go to TRS command in ExpertGPS Pro will take you directly to any township and range in 17 western US states, allowing you to locate land in the US Public Land Survey System quickly.
