In a world where just about everyone has a smart phone with mapping software in their pocket, it may sound crazy to say that a Garmin RV GPS is an essential gadget for RV travel. But we’re saying it anyway because we can’t image driving a large RV without an RV specific GPS.

This post will cover the reasons to consider an RV specific GPS, the latest GPS for RVs and our Garmin RV GPS review.

Why You Need a Garmin RV GPS

If you’re thinking, “Why would I spend that much money on something I can get on my phone for free?”, you’re not alone. We too were hesitant to make this kind of investment when there are so many (free) mobile apps on the market that seem to perform the same function. GPS units seemed like dinosaurs, something that belonged in the early 2000s along with MapQuest.

And yet. After just a few months of navigating with the Garmin RV GPS in our first motorhome, we couldn’t imagine life without it.

Reasons to Have a Garmin RV GPS

Customized Routing

Even the smallest RVs are bigger than your average sedan. An RV GPS will take your large vehicle size into account when it calculates your optimal route. If you’ve ever been heading toward a low bridge and thought, too late, “I wonder exactly how tall my rig is,” you know how important the dimensions of your RV are when it comes to routing.

The Garmin RV GPS has a profile section where you can input the width, height and length of your RV. The RV GPS we used had two profile options so we set on up for our Class A motorhome, and one for our Jeep Wrangler tow vehicle.

When we drove, we selected the RV profile. This allowed the GPS to customize the route. The mapping included relevant restrictions like low overhangs or bridges over roads and highways. This helped ensure we didn’t end up on a road with low clearance or a weight restriction.

Offline Capability

Unlike Google Maps and other mapping software on our phones, the GPS doesn’t need connectivity to work. The device will work as long as it can connect to a satellite. We never ran into a situation where the Garmin GPS could not connect.

Offline capability also means the GPS does not eat up valuable gigabytes of data. This is incredibly useful when you’re on Forest Service or BLM land looking for a boondocking spot, where service can be spotty or nonexistent.

Large Display and Intuitive Alerts

The large 7″ display size of the Garmin makes it easier to read than a cell phone screen. Yellow bars and audio notifications alert us if the road conditions are changing (sharp curve, steep grade, school zone, speed limit change, etc.). The turn-by-turn directions are clear and easy to follow. The RV GPS will also provide clear instruction on when to change lanes so that you’re in the right place for a highway division or interchange.

Steer Clear of Tolls

The RV GPS allows you to preview possible routes before a trip. If you want to avoid tolls like we did, you can make that decision in advance. The routes will show estimate time of arrival and total mileage. These estimates are specific to an RV and not to a car, which is handy when it comes to estimating arrival time. Traditional mapping software assumes that you can always go at least the speed limit, and this isn’t always the case for RVs.

See What’s Coming

An RV GPS will also show stops that RVers care about: restaurants, gas stations, banks, rest stops and RV services. If you are looking for something specific such as a Costco gas station, you can use the search feature.

Plan Your RV Road Trips

Garmin also offers a trip planning service called BaseCamp. This allows users to mark points on a map, survey the terrain in 2-D or 3-D, and share their trip with others. We didn’t used BaseCamp because we usually have no idea where we’ll be heading next, but we like features that make it easier to stay safe and connected.

Latest Garmin RV GPS

As of writing this post, these are the latest RV GPS models from Garmin.

Garmin RV 780

The Garmin RV 780 is the lowest-priced offering from Garmin ($399.99 at time of writing). Don’t let it’s ranking as “lowest-priced” fool you, though. The 780 has a ton of great features.

Garmin RV 785 with Built-in Dash Cam

Garmin Overlander

Last, but not least, there’s the Garmin Overlander, the most expensive of the lineup ($699.99 at time of writing).

In a word, the Overlander is cool. The vast majority of RVers won’t need an RV GPS unit this robust; as the name implies, it’s built for four-wheelers who venture into some tough territory.

Garmin Overlander Features:
  • On- and off-road navigation
  • Topographic maps for North and South America
  • Spoken directions with street maps for North and South America

Our Garmin RV GPS Review

The RV specific GPS unit we owned was the Garmin RV 760LMT. It is no longer in production and has been replaced with the newer models listed above. Watch the video to learn more about why we thought the Garmin was the Best RV GPS.

RV GPS Isn’t Perfect

An RV GPS review would be incomplete without an acknowledgment of its shortcomings. GPS devices aren’t perfect and here are some of the problems we had with ours.

Outdated Information or RV Access Unknown

The biggest struggle with RV GPS is that it needs to be manually updated. Unlike Google Maps or other app software that updates constantly in the cloud, your RV GPS software has been downloaded to your device. It’s only ever as accurate as the last update.

The speed limit is frequently off by 5 to 10 miles an hour, or RV access for a main road is unknown. We learned not to rely entirely on the GPS and to keep aware of signage. When RV access is unknown, the GPS will route to a road where access is known. This has led us to a few out-of-the-way and sketchy routes.

As Garmin stated on their website “Always defer to all posted road signs and road conditions when making driving decisions.”

Summary

Overall, the Garmin RV GPS is a great tool and one of the best RV GPS out there.
