Building an Overland Vehicle: Communication and Navigation

Let's explore how to outfit your vehicle with the right tech to stay safe and oriented on your adventures.

Building an Overland Vehicle: Communication and Navigation

This is part of our series: Building an Overland Vehicle: A Complete Guide to Upgrading Your Rig.

While performance enhancements give your rig the muscle to tackle tough terrain, the communication and navigation tools ensure you're tackling the right terrain – and can call for help if things go sideways. These systems are the unsung heroes of successful overlanding, keeping you on track and connected even in the most remote locations. Let's explore how to outfit your vehicle with the right tech to stay safe and oriented on your adventures.

Navigation systems are essential for overlanding, allowing you to plan routes, track your progress, and find your way in unfamiliar terrain. They combine GPS technology with detailed mapping to provide accurate location information and guidance.

GPS Units

Purpose-built off-road GPS units are a game-changer for overlanding. Many of these units can pair with your smartphone and mapping software, enhancing their functionality. It's worth noting that you can also use your phone's GPS with downloaded maps as a backup or alternative to a dedicated unit.

Popular options include the Garmin Overlander and the Garmin inReach.

Offline Mapping Software

Having access to detailed maps without cell service is crucial for overlanding, as many remote areas lack reliable connectivity. Apps like Gaia GPS or onXoffroad allow you to download detailed maps for use without cell service.

Benefits include:

  • Customizable map layers (topographic, satellite, trail systems)
  • The ability to track your route and share it with others
  • Regular updates with user-contributed trail information
  • onXoffroad premium subscription shows land ownership, which can be valuable for identifying public and private lands during your travels

Physical Maps and Compass

Never underestimate the importance of analog backups. A good topographic map and a reliable compass can be lifesavers if your electronics fail. Plus, there's something satisfying about plotting your course the old-fashioned way.


Communication Devices

Communication devices are crucial for overlanding as they provide a vital link to the outside world when you're in remote areas without cell phone coverage. They not only enhance safety by allowing you to call for help in emergencies but also enable you to stay in touch with your travel group, get weather updates, and even connect with other overlanders for tips and camaraderie.

GMRS and Ham Radios

These are excellent for group travel and short-range communication.

  • GMRS (General Mobile Radio Service) radios are license-free and offer improved range over standard walkie-talkies, making them ideal for convoy communication
  • Ham radios require a license but offer more extended range and features. They're great for connecting with other overlanders or local communities.

Remember, the best communication setup often involves a combination of devices, providing redundancy and flexibility for different situations.


As we wrap up this section, it's clear that building the perfect rig is a balance of performance, comfort, and preparedness. But before you rush out to start bolting on new gear, our next section will guide you through some crucial considerations. From legal requirements to budget constraints, the next section: Considerations Before Modifying will help you prioritize your upgrades and ensure your overlanding build is capable, compliant, and tailored to your specific needs. After all, the best overlanding rig isn't necessarily the most modified – it's the one that gets you to your destination safely and lets you enjoy the journey along the way.
