Uploading and Downloading Garmin zūmo 346 LMT-S Data

Download your Garmin zūmo 346 LMT-S waypoints, routes, and tracks to your computer

ExpertGPS can transfer Garmin zūmo 346 LMT-S waypoints, routes, and tracks through your computer's USB port. It only takes a second or two to download all of the data from your Garmin using ExpertGPS.

Upload new waypoints, routes, and tracks to your Garmin GPS

Maximize your GPS Memory

Your Garmin zūmo 346 LMT-S has limited storage space for waypoints, routes, and tracks. 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, routes, and tracks 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 Garmin zūmo 346 LMT-S waypoints, routes, and tracks

Backup your zūmo 346 LMT-S waypoints, routes, and tracks 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 zūmo 346 LMT-S, and use ExpertGPS to find and create new waypoints, routes, and tracks to download to your Garmin GPS. Before you update your Garmin zūmo 346 LMT-S 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 zūmo 346 LMT-S data is always safe.

Making Maps from your Garmin zūmo 346 LMT-S Data

Real 1:24000 USGS Topo Maps

View your Garmin zūmo 346 LMT-S waypoints, routes, and tracks 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.

Toggle between Topo, Aerial, and Color Orthophotos

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.

Give your maps a professional look

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.

Boost your Garmin GPS data entry speed 500%!

Why waste time entering new waypoints on the tiny screen of your Garmin zūmo 346 LMT-S? ExpertGPS can do it 5x faster!

Calculating Area with your Garmin zūmo 346 LMT-S

Calculate Area (Acreage) using your Garmin zūmo 346 LMT-S

Calculate area with your Garmin zūmo 346 LMT-S. ExpertGPS automatically calculates the acreage of any parcel, field, or tract no matter how irregular, when you record the boundary with your Garmin zūmo 346 LMT-S or trace it over the maps in ExpertGPS. ExpertGPS allows you to calculate acreage in three different ways:
1. Calculate area by walking a perimeter with your GPS. ExpertGPS calculates the acreage enclosed by your Garmin zūmo 346 LMT-S tracklog.
2. Calculate area by marking GPS waypoints at the corners of a field or parcel. In ExpertGPS, connect those waypoints into a route, and the acreage is automatically calculated.
3. Calculate area by tracing over a map or aerial photo. Use the Track Tool in ExpertGPS to trace the property boundary or field, and let ExpertGPS calculate the number of square feet it encloses.
