Pros / Beyond having preloaded maps on board, its accompanying mount doubles as a GPS antenna for super-precise navigation.

Cons / The device itself is bulky, as is its accompanying mount and other accessories.

 Verdict / The Rand McNally OverDryve is the most powerful, well-rounded and capable navigation GPS in our lineup.

When you think of Rand McNally, odds are you first think of paper maps, not navigation GPS. However, the company’s recent digital transition gives commercial fleet drivers and average drivers alike a powerful GPS system called OverDryve. With its highly accurate GPS antenna mount, extensive smartphone integration and easy-to-use interface, the Rand McNally OverDryve – which doubles as a Wi-Fi tablet when detached from its mount – is the best overall car GPS.

Thanks to included map updates and traffic alerts for the life of the device, you can always have the most up-to-date routes and avoid car accidents or construction delays during your commute. The GPS can also present you with alternate routes, should you want to avoid a specific road or just happen to want a more scenic drive. No matter where you’re driving, it tells you the speed limit of that particular road so that you can obey local traffic laws. It also tells you which lane you should be driving in to make your next turns.

While you’re driving, you can turn on the device’s built-in dashcam to capture a stunning road trip, or you can always keep it on in case you’re in an accident and need to provide evidence to court or your insurance company. The camera still works if you remove the device from the dock – if for instance, you need to document dents in your car, a flat tire or anything else noteworthy.

Rand McNally preloads the car GPS with 10 million points of interest – the most in the industry. These points of interest include gas stations, hotels, restaurants, stores, museums and other places, ensuring you are never stuck driving around aimlessly in an unfamiliar place. You can also quickly add and save your own favorite destinations into the system and access them whenever you need to travel there. If your commute needs to include multiple stops along the way, you can program them in – or even one at the last minute while driving – and it will automatically sort them into order by distance and navigate you to each in the most efficient route.

The OverDryve has a clean, modern design, though its build is somewhat bulky compared to the other units we reviewed. However, it’s the most powerful, precise and feature-packed unit on our comparison. Despite coming in a large box full of accessories, which may seem a little daunting at first, installation and setup for the OverDryve is simple and quick. Its interface is well-designed and intuitive, and it’s easy to find whatever option you’re looking for. The GPS connects to its mount via magnets, so it’s held sturdily in place but is also easy to remove.

As is the case with the Magellan RoadMate 7771T-LMB, it has a 7-inch capacitive touchscreen display, which makes it easy to view your navigation details like upcoming turns, the lane guidance feature and even the speed limit indicator. Intuitive icons and menu navigation make it easy to enter a specific destination address, access the device’s camera and interact with your smartphone, which easily syncs with the GPS via Bluetooth. Its built-in trip planner lets you set up all of the destinations within your road trip.

The device itself comes with a smart assistant, letting you use your voice for navigating, sending text messages, making phone calls and perusing apps. If your kids are screaming or if you have music playing, the device’s two microphones have a noise cancelling feature that can still understand you so you won’t have to shout instructions at it.

The GPS runs OverDryve OS, its native platform. One of the bonuses of such a powerful native operating system is that it affords you all sorts of capabilities beyond GPS navigation. Once you detach the device from its magnetic mount, you can use it as a regular everyday tablet. It is Wi-Fi capable and allows you to take pictures as well as download and play music, podcasts, audiobooks and games. The platform is compatible with both Android and iOS and can even pair with additional accessories, like Rand McNally’s tire pressure monitoring system and wireless backup camera.

Rand McNally has tons of information about the OverDryve available on its website, including some informational articles, product manuals and a FAQs section. You can also interact directly with the company’s support reps via live chat, phone or email, if you have a question or problem. The OverDryve ships with a one-year warranty, which is standard for this industry.

The Rand McNally OverDryve is loaded with its own native OS and all of the premium features you’d expect from a car GPS. It also has impressive battery life and its screen is the largest, highest-resolution option on the market. Its extensive smartphone integration keeps you connected while you drive, as it can interact with your phone’s assistant, play music, or call or text a friend.
