AMROOLOO Head up Display Car, OBD In-car Display, GPS Speedometer, with Multiple Reminder Functions, Suitable for All Cars

lots of info displayed on a nice little screen, selectable information and plugs directly into the port.

My Smart 1.0 unleaded car doesn't have a rev meter, temperature gauge etc.. This OBD2 gauge is perfect for me, as I want to know more other features. I like to know radiator temp. Battery voltage and other similar features. Knowing these information can help diagnose a cars condition, before it's too late. Mounting the unit on a dash was simple, and you get some double sided sticky pads included. The units 3 buttons are so easy to use and to remember. The middle one is OK and the left and right are for toggling. The screen has enough room to display sharp vivid display. Cycling through different displays look so awesome! I could display a handful of whatever I want to see, on the display. Makes driving my Smart more safer, now knowing I could see more temps, and reacting sooner than the wall socket join. Value for money.

Bought for my mk1 seat Leon cupra r and it works perfectly! Monitors a lot of systems on my car great piece of kit for the money! I highly recommend it for this car not sure about other makes and models? Also I’ve got to add in obd2 mode it’s very accurate which I was surprised about for the money!

I am happy with the purchase easy to connect and set up. Good variety of options for display, nice that included are options for ‘securing’. Very accurate.Lost a star because I can't get it to turn off on the voltage or COM settings, but will be trying again soon as this may be user error as looking at the web, others have managed to get it to work so I probably just need more patience and time, but it's not intuitive or easy and very trial and error! Overall though, happy with this purchase.

After 10 minutes of driving, the display freezes and the device makes a loud beep noise. Only fix is to unplug it from OBD and then plug it again. But that is just to have same effect in another 10-15 mins.

Works great on my 2008 smart 451. The instrument cluster on the smart is very basic with a speedo and fuel gauge that's it. This hud is great now I have a rev counter, water temperature gauge and turbo boost guage and much more. Even looks like it was made for the car. Very pleased

Unlike a more expensive MR TOOLS product that failed me in so many ways and was swiftly returned this cheaper alternative works perfectly The only feature missing is an inclination indication. It's a neat gadget that doesn't look out of place in my car. You can easily mount it to the windscreen or fix it on your dashboard. Everything you need is in the box and the OBD connector is a slim flat fit so no worries if your OBD socket is in a tight less roomy space. Very configurable and power down into sleep mode can be set to accommodate even those Hybrid Cars. Brilliant...

Works perfectly for my 2016 Toyota RAV4
