How do I know if I need a GPS kit for the speedometer in my GlowShift gauge package?Updated an hour ago

A GPS kit is recommended if your vehicle does not have a Vehicle Speed Sensor (VSS) or if your original speedometer is cable-driven. A VSS provides a signal that the speedometer uses to calculate your vehicle’s speed. If your vehicle does not have this sensor or uses a mechanical speedometer cable instead of an electronic speed signal, the GPS kit can provide speed readings using GPS technology.

The GPS kit allows your GlowShift speedometer to determine your vehicle’s speed without connecting to a factory VSS or speedometer cable. This makes it a useful option for older vehicles, classic cars, and custom builds that lack a compatible electronic speed signal.
