1. Types of RV GPS

There are 3 main types of GPS systems for RVs.

Handheld System: As its name suggests, the handheld system is portable, and you usually use it by holding it in your hands. It is by far the most flexible type of RV GPS systems.

However, the main disadvantage of this system is that it is usually smaller, with a small display that may make it difficult to read.

Wrist GPS Tracking: The wrist GPS tracking system is worn like a watch, on the wrist and is usually extremely lightweight and compact.

This type of GPS tracking system usually has limited functionalities and equipped with a very small screen.

However, its main advantage is that it is very easy to use and are quite practical, especially during hiking. Of course, this type of GPS is not suitable for driving.

Built-in GPS System: Most vehicles nowadays come with a built-in GPS system.

This GPS usually works hand-in-hand with your car audio system, and you can easily switch between one or the other.

The biggest advantage of the built-in GPS system is that it offers you a large screen that is easy to read both during the day as well as at night.

For driving long distances in an RV, the built-in GPS is generally the best RV GPS navigation system that you can purchase.

2. Screen Size

The screen of the GPS system is where everything is displayed. Therefore, it needs to be sufficiently big to be easily seen.

In most cases, a screen size of at least 5 inches will be easily readable by anyone at a normal driver's distance.

Furthermore, most modern-day GPS systems for RVs are usually touchscreen, which makes it much easier to use than older systems.

3. Resolution

In addition to the screen size, the resolution of the GPS system is also an important factor to consider. The higher the resolution, the crisper the image will be and hence, easier to read.

As far as possible, try to go with a model that offers a resolution of at least 800 x 480. Of course, the more, the better when it comes to the resolution.

4. Controls

The GPS system for RV offers you different types of controls. Most quality models are voice-activated, which means that they will respond to your voice without the need of having any physical interactions with the GPS.

In addition, the versatility of controls is important. So, you must also be able to adjust the GPS system, like inputting a new destination or changing the route by using the inbuilt button of the GPS.

5. Frequency of Your Trip

If you frequently make the same route, then your GPS system would have the possibility to save that destination. This will allow you to quickly and easily change your destination on demand.

Furthermore, if you want to visit a destination that you have never been before, then your GPS system must also be equipped with up-to-date maps.

In fact, most reputable manufacturers will provide you with free lifetime map updates for this very purpose.

6. Predictive Data Entry

A predictive data entry system in a GPS is simply the way that the GPS system adapts to your driving patterns.

For example, if you frequently travel to a specific destination, then a GPS system equipped with predictive data entry may start offering you a better alternative route to your destination.

7. Bluetooth

Many people drive an RV or truck with Bluetooth headsets. A big advantage of some GPS systems that are voice-activated is that they are equipped with Bluetooth.

This means that you can input your destination or change a route by simply using your voice.

And since you will be using a Bluetooth headset, your voice will be crystal clear, and the GPS system will have no problem understanding you.

This is especially important if you usually drive in noisy environments with traffic noise or music in the background.

8. Ease to Install

As with most RV accessories, the GPS system must be very easy to install. Most quality models come with a detailed user manual that will not only show you how to use it properly but also install it appropriately.


As we have seen, the GPS system is vital if you have an RV. Since you will be traveling a lot, you will never get lost while driving with the GPS system.

Also, it is perfectly safe and fully legal to install in an RV. Not to mention that it is extremely easy to use. If you have never used a GPS system before, then don't worry as it is an extremely beginner-friendly device.

If you have read our RV GPS review above, and still not decided on which GPS system to purchase, then read the review again. If you have, then we wish you good luck on your travels.
