Review on 🚀 ELING 85mm GPS Speedometer Odometer - Adjustable Mileage & Overspeed Alarm for Boat, Car, Truck, Motorcycle (125MPH) by Andy Kucrud

Eling quickly sent a 120 mph speedometer, it arrived within a week. Thanks. Installed it on my 1974 BMW. It fits exactly into the original hole on the instrument cluster. The black frame is on the surface in front. The turn signal and high beam wires connect to the existing turn signal switch wires. The power supply for the speedometer, the backlight and the external switch is connected to the source after the ignition is switched on. The antenna is mounted at the bottom center of the windshield. Followed the starting instructions and had a working speedometer. Seems a bit slow to react to speed changes at this point. Although it's as accurate as the Up on my phone at maintaining speed in traffic. I'm happy with that. There are few instructions as I could not set the odometer to the actual mileage of my car. Can the seller or someone please walk me through the steps to set up the odometer? And buy if you need a replacement. The seller was quick to answer my question about setting up an Odos. Now it is installed. You must have access to the back button. Thanks.
