KAOLALI 85mm GPS Speedometer Gauge 0‑200KM/H Boat Speedometer Waterproof Marine Speed Gauge Meter with COG Trip Total Mileage for Car Truck Motorcycle 7 Colors Backlit 9-32V

Works perfect like description

5 minute install. Sat in boat on trailer while being towed by my truck. Boat and truck speed identical. No more clogged pickup tube. Sweet.

Easy to install, works once attached, and accurate for milage and speed. Working great for my 1960 Jeep Willy Pickup Rat Rod build.

The speedometer works very well but had two drawbacks for my application:1. The glass (not plastic) face cover caused so much reflection that I could not read the dial.2. The menu and set buttons built into the back of the instrument would be inaccessible in my application.I mounted the speedometer in the instrument cluster of my '97 Geo Tracker, replacing the factory speedometer dial. Because it was completely enclosed in the factory housing, I removed the glass (carefully breaking it) and cut open the back of the plastic housing so I could wire in two remote buttons. I'm very pleased with how everything worked out and the price was exceptionally good for this type of instrument.

I am very disappointed . Did not work at all, cracked and broke during install, Doubt I will be able to get a replacement or refund

Just remember your last tech idle number and set this unit to that so far seems to work
