Review on MOTOR METER RACING W Pro GPS Speedometer Odometer Waterproof for Car Boat Motorcycle: Black Dial, White LED, and GPS Sensor Included by Vincent Hurst

Tried several times to fix the speedometer cable. Lasts for a while and then self-destructs. I got tired of changing them and decided to use something that doesn't match the gearing. Bought this unit, incredibly easy to install. Seems very accurate and responsive. The ONLY gripe I have is that they have no instructions on how to set the odometer reading on these new units to copy the old one. After contacting support, they responded. Press the button on the back five times. Pause for a second, then tap it again. This allows you to subtract miles from the odometer. Touch it a second time and it will be added to the odometer. Now my new setup exactly duplicates the old mileage. Cool, so far so good!
