What to Consider When Choosing GPS Speedometers
Types
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, and so on.
Key Features
Compatibility
Many GPS speedometers are compatible with nearly all vehicles as well as motorcycles, ATVs, and boats. Some 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.
GPS Speedometer Pricing
GPS speedometers exist on a rather broad price spectrum. Most budget-friendly options sit between $20-$80, which features generally driving pricing. However, premium options can bring in far more, with quality being a primary factor behind the price tag. It's also worth mentioning that sets featuring different gauges also sit beyond the typical range.
