Being able to adjust the speedometer makes a big difference. It now tracks with my cruise control setting nearly perfectly. The update rate is quite good as well, not super fast but quite good.The small sticky pad that come with the unit does not work so well; the unit kept falling over. I bought a non-skid pad and set it on that. I am also using a white washcloth to cover it when parked in sunlight to keep it cool until I need it again.

I like that it is small and mounted right to my dash. It is very bright so very easy and clear to see for night driving. I can not rate the mileage aspect because I have not used that feature. I bought because my speedometer is hard to see and not very clear to read every little dash line mark. This was definitely worth the money and I love that I can use it day or night and know my exact speed.

Worst damn thing I’ve ever bought. I have tried 2 of these and they don’t stay in contact with gps satellites. I have tried everything they say to fix it and no response. I’m in the open and all it does is search but nothing else. Won’t ever buy one of these again

I got this for my motorcycle because bike's built-in speedometer is not accurate in mph. This speedometer works, and is reasonably accurate, but it's problematic because it takes several minutes from a cold boot (even if I only turn it off for a few seconds) until it connects to satellites and starts displaying your speed. I have it wired into the motorcycle's 12 volt system with a 12V->5V converter, but of course, when ignition is off, the gps is turned off in order to conserve the motorcycle's battery. I need to find another gps speedometer that has a faster cold boot than this one, so that I can use it quickly after start up.

Used to replace a broken speedo on a vintage car. Pay big bucks to fix the speedo or do this. It was an easy choice.

Takes a while to connect to gps and isn't completely accurate out of the box but it does work once it connects to gps and it's better than the broken speedometer in my truck.

Don't get me wrong I really love my Lexus products. The second worst design flaw is the speedometer. Hate the small, dim, illegible screen. Can't arcuately check the speed by guessing at the position of the needle in a 20 mph span of hash marks, which is frequently blocked entirely by the position of my hands on the wheel anyway. This addon speedometer fits perfectly and is highly visible on the dash above the instrument panel. Problem: it overstates the MPH by 1-2 after 65 MPH.

All I want to use this for is for the direction and clock. Direction shows but cannot figure out how to set the clock. Directs are junk and don't help
