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

Ok the instructions aren't great but they're good enough to get the job done. I installed this in my vintage RV that had a bad speedometer and it didn't take long to hook it up to the existing wiring and set it up with the old mileage showing on the RV odometer. I love that I can do without the extra lights for turn signals and high beam on this particular model, which will be nice when I make other improvements to the instrument cluster. I also chose it because 60 mph is straight. An RV doesn't need a 125 mph speedometer, but in my case it's easier to read when the needle is straight.
