Digital GPS Speedometer

This thing works fine. It’s a little small so don’t put it too far away.

2012 mini cooper, for coolant temp gauge

Bought a new truck and where the steering wheel is most comfortable I could only see a small part of both the tachometer (0-1000 rpm) and the speedometer (0-30 mph). Definitely needed something. My last HUD was a projection type that projected onto the inside of the windshield but in the bright AZ sun it could be hard to see at times.This unit definitely solves that problem. At full display brightness it's very easy to see even in the bright sun. It was pretty easy to setup & use with the OBD II port. It was also easy to navigate right out of the box. Their abbreviations for items are a bit strange but there's an abbreviation key in the manual so you just have to get familiar with them.I bought this one because it had an audible alarm that I wanted to setup for a highway speed to let me know when I was getting a lead foot. Turns out I could set an alarm for both the tachometer AND speedometer. Very nice feature as I have a sequential shifter that I could use the tach alarm for and still have the speedo alarm. There is also an LED that outlines the display that flashes when the alarm goes off. That could be brighter and this is my only negative, thus 4 stars instead of 5.

No funciona, si enciende bien pero no lee los datos correctamente, solo pone números aleatorios y porcentajes que no tienen nada que ver.Tengo Jeep 2010
