4" GPS Speedometer | 160 MPH | Pontiac Design

We are proud to have a lifetime warranty on our circuit boards, to the original purchaser. If it is resold it would not be covered under warranty, we can still repair however there would be a charge depending on the repair needed.

These warranties do not apply in the event the gauge is improperly used, installed, or modified.

They are incredibly simple and straightforward to install! Our GPS Speedometers connect to the Global Positioning System through an antenna, and don't require a transmission sensor. (The antennas are included with the GPS Speedometers, too!) This makes them very easy to install in vehicles that lack electronic sensor output.

The GPS speedometer updates 4 to 5 times per second. The update rate is fast enough to not show any noticeable delay in keeping up with speed under hard acceleration or braking. Our GPS speedometer are used without issues in many performance cars!

If you exceed your speedometer's maximum speed, the pointer will remain at the maximum speed position, and will not move below the maximum speed position until your speed drops back into a readable range.

Luckily for all of the speed-fiends out there, this will NOT damage the speedometer.

If the speed exceeds the analog range and you are using a GPS speedometer with an LCD display then you can use the digital speed display feature to view your current speed.

Our GPS speedometers rarely drop signal. They use a powerful 'active' antenna which perform exceptionally well in all driving environments, including tall buildings, canyons, and extreme weather such as rain and snow. In most cases, the only time you will experience a signal loss is while driving in tunnels or in parking garages.

No, but we offer three different antenna lengths for you to choose from: 5', 9.8' and 15'.

The best location for the GPS antenna to be mounted is on the roof of the vehicle. The GPS antenna is waterproof and magnetic. If the roof is inaccessible, the antenna can be mounted on the top of the dashboard in a place with maximum exposure to the sky.

Metal will block the GPS signal, but the GPS antenna can receive a signal through thin materials like wood, glass, fiberglass, and plastic.

Yes, we can do that for you!

Please tell us your mileage in the 'Order Comments', and we will program your odometer when we build your gauge.

If you already own one of these speedometers you can send it back to us and we can program the miles into the odometer (shipping charges will apply).
