Product description
MAIMEIMI HUD SPEEDOMETER – SAFER DRIVING 
The MAIMEIMI heads up display for cars is engineered to enable you to concentrate more on the road and perceive the driving data more intuitively, avoiding the distraction of looking downward at the instrument, thereby enhancing your driving experience and rendering the journey safer.
PRECAUTIONS FOR USE
Working Voltage 11V~18Vdc (12Vdc/200mA). For vehicles with voltage higher than 24V, please use a USB cable. System OBD/GPS(After connecting the power supply, you can choose which system to use) Please Note If you do not use the car for a long time, please remember to unplug the power plug to save power. Manual Speed Correction If you find that the speed does not match the speed of your car’s meter, you can adjust it as following steps: Step 1 Confirm that your speed unit is MPH, if not, please enter the speed unit setting module to switch(refer to the user manual for the method of entering the setting menu), ensure that the speed unit is MPH, then you could follow step 2. Step 2 Speed fine-tuning: Enter speed unit setting module, you will see the initial value is 107, assuming that your meter value is 100 mph, and the HUD is 105 mph, that is, the HUD is 5mph faster than the meter value, then you need to subtract 5mph from the initial value 107, which means that you need to adjust the initial value to 102. So the secret of the adjustment is to add/subtract the difference between the meter and the HUD using the initial value 107. Step 3 If the speed of the instrument and HUD cannot be matched by the above two steps, we suggest that you enter factory reset module, restore the factory Settings, and then measure the speed again or repeat the above two steps for adjustment. Step 4 If you encounter any problems in the adjustment process or think that the HUD does not meet your expectations, please do not worry, we will provide you with more careful after-sales service.

Perfect on dash speedometer!
Nice design. Pretty accurate. Actually told me my speedometer was off. It was correct. Its real time information from the engine.

Don’t unplug your car battery while it’s installed
Fried itself after 2 month of usage it worked well for the time it worked properly did not work with my obd2 port only gps speedometer worked it was accurate but I would have liked it more if it didn’t fry itself and actually pulled data from the obd2 port instead of power

good for the price and also a 12v system
I love the display, it is used on a Gokart with a 12v system, it is gps tracked some if you go into a garage it will lose signal or under a bridge for a few seconds and then reconnect, multiple different interfaces with different reasons for them, unfortunately mine seems to power off after a few minutes due to inactivity but also it comes back on when touched. accuracy is good I believe and easy to install

You can do better
Device was delivered in perfect working condition, unfortunately that’s not enough. PSI for turbo does not work, led ambient lights work but are cheaply made with no ‘fade in and out’ instead it’s a full color ‘click’ color switch which is annoying and cheap looking, the control single-button is the worst way to control the display and make adjustments to displays as in which info you want displayed. The accuracy of readings via OBD is hard to get wrong but the G sensor is flaky and is unusable. Unit is overpriced and definitely will be getting pulled out and switched asap. To any potential buyer, you can do better! Extra 10 bucks can get u a bigger, more accurate, less buggy, easier to adjust OBD display. On a positive note, the unit does stick well to the window with provided double sided tape – but the screw the keeps the angle of display is weak and display dips and sags no matter how tight it is.

Using this as digital speedometer but wanted more.
I purchased this to see how turbo boost is used by engine. Can’t make sense of turbo display. Instead I found the display of speed more useful. I don’t have to look at analog speedometer to determine speed.UPDATE – My truck is parked outside in hot Florida summer and found this unit is not usable when left in the sun all day. If I cool unit down it will work again. Dont bother buying this useless device.
