How We Tested

Our reviewers spent 24 hours testing one of our readers' favorite car GPS trackers. To get the most well-rounded results, they installed it in their own vehicles, drove for hundreds of miles, and observed its performance. We asked our testers to consider the most important features when using this car GPS tracker, from its power source to its special features (like daily driving reports). We've outlined the key takeaways here so that you, too, know what to look for when shopping.

What to Look for in a Car GPS Tracker

Price - GPS trackers can run anywhere from $25 to over $100, so it’s important to think about what you want to spend. But there’s more than just the upfront cost to take into consideration — many operators charge a monthly fee to store your vehicle’s GPS data in the cloud. If you’re looking for long-term data but don’t want to pay monthly, it might be worth paying more upfront to avoid these kinds of charges.

Special features - If the only thing you want from your device is tracking, your decision is probably pretty straightforward — but many of the options on our list can do a lot more. From daily driving reports and Alexa integration to diagnosing engine trouble, these models have many different features that may be relevant to your needs.

Power - The question of battery versus plugged in is relevant for most electronics, and car GPS trackers are no exception. Many of these devices have long-term batteries, while others connect to your car. It’s important to consider whether you want to worry about recharging or replacing batteries, or whether you’d like the device to always be on whenever your car is running.

This car GPS tracker impressed our testers with its excellent battery life, ease of use, and accuracy. One tester explained: “This tracker shows the speed of the vehicle and the map integration shows its exact location, which is great.” Our testers didn’t love the weight — it's heavy — and wished it came with a dashboard mount. One tester also had an experience with it shutting down in the middle of his trip. “I had put the tracker on my motorcycle for a 1225-mile ride so that my wife could track me and see that I'm safe,” he said. “But we noticed that the tracker stopped working after 256 miles and wouldn’t restart. We had to call the customer support a couple of times to get it started again.”
