Sometimes your adventure goes beyond what’s available in the default Magellan trail maps. Whether you’ve mapped a route using Gaia GPS, downloaded a trail from AllTrails or GPX Studio, or received a track from a friend, the Magellan TRX7 and TRX7 CS Pro make it easy to install and navigate custom GPX files.
In this 2025 tutorial, we’ll walk you through the exact process of importing external GPX trails into your Magellan off-road GPS.
📁 What Is a GPX File?
A GPX (GPS Exchange Format) file is a universal GPS data format that contains:
- 📍 Waypoints (locations)
- 🛣️ Track lines (paths)
- 🔄 Routes (turn-by-turn directions)
- 📝 Notes or metadata
These can be exported from popular trail-planning tools and imported into your TRX7 for use offline.
🖥️ Step 1: Get or Create Your Custom GPX File
You can:
- 🧭 Create a GPX using Caltopo, GaiaGPS, GPX Studio, or Garmin BaseCamp
- ⬇️ Download from sites like:
- 💾 Save the file to your PC (example:
arizona_mojave_trail.gpx)
🎯 Make sure the file includes track points or route data, not just a waypoint.
🔌 Step 2: Transfer GPX File to TRX7 via USB
- Plug your TRX7 / CS Pro into your computer using USB
- Wait for it to appear as a removable storage drive
- Open the drive and locate the /GPX/ folder
- Drag your
.gpxfile into that folder - Safely eject the GPS and unplug it
📲 Step 3: Import the GPX on Your Device
- Power on your TRX7
- Go to Saved Trails > Import from GPX
- Select the trail you just transferred
- The custom route will load on your map interface
- Tap Start Trail to begin navigation or analyze it before your trip
☁️ Alternate Method: Upload GPX via SmartGPS Eco
If you prefer wireless syncing:
- Go to https://www.smartgpseco.com
- Log in with the same account used on your TRX7
- Go to Journal > Import File
- Upload your
.gpxfile - On your TRX7, connect to Wi-Fi
- Tap Settings > Sync Now
- The trail will appear in your Journal or Tracks
