GPS Speedometer Sensor Adapter Kit - Easy Roof Antenna Install

In this review the GlowShift GPS Speedometer Sensor Adapter Kit is evaluated for drivers who want a quick way to add accurate speed readouts without complex vehicle wiring. The bottom line: it is ideal for owners of compatible speedometer gauges who value plug-and-play simplicity and dependable GPS-derived speed. Installation is straightforward, and the kit ships with clear step-by-step instructions, making it a practical choice for hobbyists or installers who need an alternative to sending speed pulses through the vehicle harness.

Key Features

• Direct GPS speed readout: Provides vehicle speed using satellite signals so users can view MPH or KPH without tapping into the vehicle speed sensor.
• Universal compatibility: Works with any GlowShift speedometer gauge, making it a simple add-on for existing GlowShift installations.
• Roof or trunk antenna mount: The included antenna installs to the roof or top of the trunk for good sky view and consistent signal reception.
• Generous antenna cable: The GPS antenna includes 6-1/2 ft of wire to reach most dash gauge positions without splicing.
• Compact harness and sensor: Includes a GPS signal harness with 1 ft of wire and a small GPS sensor for tidy mounting under dash or behind the gauge cluster.
• Support and warranty: Backed by a one-year limited warranty and free lifetime technical support to assist with setup or troubleshooting.

Who It's For

The kit is best for vehicle owners who already use or plan to use a GlowShift speedometer gauge and want the convenience of a GPS-derived speed display without running a long vehicle speed signal. It suits DIY installers and professional shops that prefer a non-invasive solution to measure driving speed in both MPH and KPH.

It is less appropriate for users who require integrated OEM-style speed pulse input to the factory cluster or for vehicles parked under dense canopy where GPS reception could be unreliable. Those needing factory instrument integration should consider other sensor options.
