    However, the OBDII mode is only compatible with 2008 vehicles and newer. It may also have some lag when displaying some information, and while you can change the color of the three sections where numerical values are displayed, you can't change the color of the gauges.

    Benefits of GPS Speedometers

    • Avoid tickets. No matter what type of vehicle you drive, you may inadvertently surpass the speed limit from time to time. A GPS speedometer ensures that you're obeying local traffic laws.
    • Avoid costly repairs. If your vehicle's internal speedometer breaks or stops working, it can be costly to repair. Instead of spending a lot of money on an OEM replacement, purchase an aftermarket GPS speedometer instead.
    • Versatility. Many GPS speedometers display more than just driving speed. They also output mileage, voltage, engine RPM, and much more. Some even have advanced features such as brake performance tests.

    Types of GPS Speedometers

    Round Gauge

    This type of GPS speedometer is intended to directly replace the unit that's currently in your vehicle, motorcycle, boat, etc. It's a round gauge, and you need to check the dimensions to make sure that it will fit properly in your dashboard panel. Most of these GPS speedometers are fairly basic when it comes to the features they provide.

    HUD (Heads Up Display)

    This type of speedometer is usually mounted on top of or underneath the dashboard. It can be round or rectangular in shape, and you don't need to remove your old speedometer for it to work. Some project driving data on the windshield, while others simply display it on the unit itself. Typically, these devices have numerous functions and modes to provide information such as engine RPM, water temperature, battery voltage, etc.

    GPS Speedometer Pricing

    • $30-$80: Many GPS speedometers are reasonably-priced. Those on the lower end of the spectrum tend to have fewer features and are more simple in operation. More advanced units have a variety of modes and can be more complex when it comes to the interface.
    • $80 and up: Full system setups, such as the MOTOR METER RACING W Pro Series 6 Gauge Set GPS Speedometer, can be very costly. But they feature several gauges and are designed to create a custom look on your vehicle. 

    Key Features

    Compatibility

    Many GPS speedometers are compatible with nearly all vehicles as well as motorcycles, ATVs, boats, etc. Many of them are plug-and-play installations, and you simply insert the cord into an auxiliary plug or a USB port for operation. However, some options/models only work on newer vehicles, so make sure to check before making a purchase.

    Size

    If you're purchasing a GPS speedometer to directly replace a broken internal speedometer, it's critical that you check the dimensions to ensure that it fits properly into the dashboard panel. As for HUD units, they are designed to be small, but some are less conspicuous than others. Choose one that will not distract you if it's in your line of sight.

    Accuracy

    The whole reason for purchasing a GPS speedometer is to determine the exact speed that your vehicle is traveling. While all brands strive to be as accurate as possible, some are better than others. Also, some devices receive stronger signals than their rivals and are less likely to drop a signal.

    Quality

    Look for units that are made out of good-quality materials. Some are more durable than others because they are dustproof and waterproof. Others have anti-fog properties. The best way to determine if a device is well-built is by reading customer reviews and seeing what they say about the product's longevity.

    Other Considerations

    • Added Features: Many GPS speedometers do much more than just calculate the driving speed. Several brands have high-tech features that alert you to the engine's RPM, battery voltage, and even the altitude in which you're traveling. These added features can be very convenient and keep you on the pulse when it comes to your vehicle's operation.
    • Appearance: If you're a car enthusiast, your vehicle’s aesthetics are very important. Some built-in GPS speedometers have very sleek designs and can really make your car's dashboard pop. There are also some HUD units that are pretty cool-looking. Or you may choose to get a device that’s small and unobtrusive so it doesn’t spoil the clean lines of your car’s interior.

    Tips

    • Position your GPS speedometer in a strategic location where you can easily read it. Accessing the readings enables you to tell the speed at which you are driving. You can then adjust your speed if necessary.
    • Ensure that your speedometer lights are working when driving at night. The lights help enhance the device’s readability. With increased visibility, you can accurately tell your driving speed, enabling you to drive safely and efficiently.
    • Avoid exposing your speedometer to a lot of moisture. Too much moisture causes mist on the display, which inhibits clear visibility. Once its readability is compromised, you cannot accurately tell your driving speed.

    FAQs

    Q: Do GPS speedometers have internal batteries?

    A: Some GPS speedometers have batteries, while others do not. Inquire about the specific model you intend to buy if you prefer one with a battery.

    Q: Is it possible to adjust the GPS antenna on a speedometer?

    A: Yes, you can adjust your GPS antenna to the length that you prefer. The maximum length is, however, dependent on your particular device.

    Q: Which is the best position to mount the GPS antenna on my car?

    A: You should place the antenna in a position where it uninterruptedly faces the sky. This enables it to draw information from the satellite for accurate readings.
