Riders upgrading their navigation setup inevitably hit the same question: is a dedicated motorcycle GPS actually worth the extra cost, or can a car GPS get the job done? The short answer is that it depends entirely on how and where you ride. The longer answer involves glove-friendly screens, IPX7 weatherproofing, vibration tolerance, and a mounting system that won’t loosen on a dirt road. To make the comparison concrete, we’re looking at two current Garmin models: the Garmin DriveSmart 71 EX, one of the better car GPS units available today, and the Garmin Zumo XT2, Garmin’s flagship motorcycle navigator.
Motorcycle GPS units like the Garmin Zumo XT2 are purpose-built for vibration, weather, and gloved hands.

Why Motorcycle GPS Units Are Built Differently
A car GPS is engineered for the inside of a climate-controlled cabin. It sits on a padded dash, protected from the elements, used with bare fingers, and replaced the moment it falls off the suction cup. None of that applies on a motorcycle.
Riders face direct sun, rain, highway vibration, and the constant need to operate controls while wearing gloves. A device that can’t handle those conditions becomes a safety liability. Motorcycle GPS units like the Zumo XT2 are designed around these realities from the ground up: waterproof to IPX7, built to survive sustained handlebar vibration, and equipped with a touchscreen that responds to gloved input. They also include mounting hardware rated for motorcycles, typically metal RAM-style ball-and-socket systems that won’t loosen at speed.
Garmin DriveSmart 71 EX: A Strong Car GPS That Falls Short on Bikes
The Garmin DriveSmart 71 EX is one of the better consumer car GPS units Garmin makes. The 6.95-inch edge-to-edge touchscreen is bright and sharp, and the interface is genuinely easy to use in a car. It includes built-in live traffic, Wi-Fi map updates, Garmin Voice Assist for hands-free control, and driver alerts for sharp curves, school zones, and speed cameras. For daily driving and road trips in a vehicle, it’s hard to fault.
The problems emerge the moment you put it on a motorcycle. The DriveSmart 71 EX has no weatherproofing. A rain shower can kill it. Its touchscreen is not calibrated for gloved input, which means you’re taking a hand off the bars and removing a glove to change a route. The suction cup and dashboard mount included in the box are not appropriate for handlebar mounting, and the device lacks the vibration tolerance needed for sustained off-road or highway riding. It also carries no topographic maps, no adventurous routing, and no way to track group rides.
Garmin Zumo XT2: Built for the Road, the Rain, and the Twisties
The Garmin Zumo XT2 starts where the DriveSmart leaves off. The 6-inch HD display is 15 percent larger than its predecessor and works in both landscape and portrait orientation. Critically, it responds to gloved fingers, so you can adjust your route without pulling over. The IPX7 rating means it handles rain without issue. The internal build tolerates the vibration profile of a motorcycle engine and rough terrain.
Beyond durability, the Zumo XT2 adds features car GPS units simply don’t offer. Adventurous Routing seeks out twisty roads and elevation changes rather than the fastest highway route. The Visual Route Planner lets you plan directly on the device or via the Garmin Tread app on your phone. Preloaded topographic maps give you full terrain context, including satellite imagery, for off-road and dual-sport riding. Group ride tracking shows other riders’ positions on your screen in real time. Bluetooth pairs to helmet headsets for audio navigation and music from your phone.
The mount situation is also handled properly. The Zumo XT2 ships with a metal RAM ball-and-socket mount rated for motorcycle handlebars. It doesn’t rattle, it doesn’t creep, and it doesn’t need a suction cup.
When a Car GPS Is Actually Fine on a Motorcycle
There are scenarios where a car GPS makes sense. If you ride occasionally, stay local, and only go out in dry weather, the extra investment in a motorcycle GPS may not be justified. A car GPS paired with a quality RAM mount and a waterproof case can cover short fair-weather trips without issue. Just understand what you’re giving up: no glove compatibility, no weatherproofing, no topo maps, and a mount solution that requires aftermarket parts to work safely.
For commuters and casual weekend riders in mild climates, that tradeoff is manageable. For anyone riding long distances, in variable weather, or on unpaved roads, a dedicated motorcycle GPS is not a luxury upgrade. It’s the appropriate tool.
Verdict
The Garmin DriveSmart 71 EX is an excellent car GPS for drivers. It is not an appropriate choice for regular motorcycle use. The Garmin Zumo XT2 costs more because it does more: it’s weatherproof, glove-friendly, vibration-tolerant, and ships with a proper metal motorcycle mount. If you ride frequently, in variable conditions, or for long distances, the Zumo XT2 is the right call. If you’re a fair-weather occasional rider who already owns a car GPS and wants to try it on the bike first, that’s a reasonable starting point, as long as you go in knowing the limitations.
Frequently Asked Questions
Can I use a car GPS on a motorcycle?
Yes, with a RAM mount and hardwired power connection. But car GPS units are not waterproof, not glove-friendly, and not rated for motorcycle vibration. They work for casual, fair-weather riding. They are not a long-term solution for regular riders.
What makes the Garmin Zumo XT2 different from a car GPS?
The Zumo XT2 is designed specifically for motorcycle use. It has a glove-friendly touchscreen, IPX7 weatherproofing, motorcycle vibration tolerance, preloaded topographic maps, Adventurous Routing, group ride tracking, and a metal RAM motorcycle mount in the box. None of those features appear in any Garmin car GPS.
Does the Garmin Zumo XT2 include a mount?
Yes. It ships with a metal RAM ball-and-socket mount designed for motorcycle handlebars. Note that it uses 12V DC wiring and is not compatible with the original Zumo XT mount, which ran on 5V DC.
Does the Garmin DriveSmart 71 EX have live traffic?
Yes. The DriveSmart 71 EX includes live traffic via a built-in receiver at no ongoing cost. The Zumo XT2 routes traffic data through a paired smartphone using the Tread app.
Is the Garmin Zumo XT2 waterproof?
Yes. It carries an IPX7 rating, meaning it can be submerged in up to one meter of water for 30 minutes. In practice, this means it handles rain, road spray, and washing without issue.
Do motorcycle GPS units cost more than car GPS units?
Yes, typically by a significant margin. The added cost reflects the ruggedized build, glove-compatible touchscreen, waterproof rating, motorcycle-grade vibration tolerance, topo map data, and rider-specific features like Adventurous Routing and group tracking.
