## Description

Product description SinoTrack Heads Up Display GPS Speedometer Why choose our Universal Car Heads Up Display? SinoTrack technology team is committed to developing products for car enthusiasts and we never cease to offer our customers cost-effective products such as the Digital GPS Speedometer for Car. Not only is it designed to allow drivers to see their speed and driving time with a flat view while driving, but most importantly it is equipped with speeding alerts and fatigue alerts for driver safety, making it an essential safety accessory for car travel enthusiasts/people who need to drive for long periods of time. SinoTrack car speedometer HUD equipped with an HD LCD display. Unlike traditional HUDs, which need to be projected on a transparent sheet to view the data, traditional HUDs will affect the clarity in strong sunlight, which is not conducive to driving safety. NOTE The working voltage of the speedometer is 5V, it is forbidden to use a voltage higher than 5V as the power supply. Please do not use high voltage or fast charging to charge the product, otherwise, it will affect the product's life and normal use. The reason of the speedometer can not connect to satellites Please help to check if there is a metal film or a shield installed on the car. If so, this situation will be very slow or difficult to search for GPS. Please try to reconnect the power, and then get the car window to receive the signal, in general, about 2 minutes to search the GPS. Please try to restore the factory settings: Press and hold the wheel button to enter the 7 setting item, adjust the value to "1" and then long press to confirm it. Any connection or installation doubts about the product will solve by the SinoTrack team, we will provide a solution to your satisfaction. Convenient, High-definintion, Multi-functional GPS Heads-up Display Compatibility for All Vehicle How to set it for getting a more accurate display? Connect the HUD display to your car The satellite is flashing and searching for a star When the satellite stops flashing, press the key button and hold to enter setting item 6 to adjust the calibration local time Check if the speed unit is accurate, you can go to item 5 to set the speed unit to MPH/KMH, i.e. "1"/"0" Fine-tune the speed to be accurate About the value of 107, long press the wheel key to enter the first item, and we can see the default car speed is 107. If the speedometer shows faster than the car dashboard speed meter, then 107 needs to be reduced downward（107-？） If the speedometer shows slower than the dashboard, 107 needs to be increased upward（107+？) The difference in value will be adjusted by how much. For example, if the car dash speed display "19" mph and the SinoTrack speedometer shows"13 mph", then you can enter the 1 setting item and toggle the wheel key to the right to increase the parameter value "107" to 113 (107+6), then press and hold the wheel key vertically to save and exit, the speed calibration is complete. Unable to connect to the satellite 1. Change position: Drive the car to an open and unobstructed area, let it stand still for a few minutes, and observe if you can receive the signal. 2. Remove obstructions: Clean the dashboard, especially the metal objects in front of the speedometer. Try to temporarily move the device to the middle position directly below the front windshield (the signal is usually the best). 3. Check the film: Check if the front windshield is covered with a metal film. You can try to temporarily extend the speedometer out of the window when the vehicle is stationary and safe to see if it can immediately detect stars. If possible, it's basically certain that it's a problem with the film application. SinoTrack HUD Display Speedometer Features OverSpeed Alarm& Fatigue Alerts Speed alarm after speed reaches the set default value of 150MP/H; Fatigue alert after driving continuously for more than the default value of 4.0 hours; Default values can be changed manually, over-speed setting (0-250), continuous driving (1-8) HD Display Anytime Equipped light-sensitive screens with an automatic dimming function, which auto-adjust makes the display very clear in daylight/night/bright light/low light conditions. You also can enter the setting “4” to set the specified brightness. Intelligent Technology Chip Professional scheme design makes the performance more powerful: high-performance processing chip, super performance and compatibility, dual-running memory, and dual-core processor to ensure smooth high-speed operation Value Adjust by Wave Button Short press in: switch the display mode (confirm the option after entering the setting) Long press in: enter the setting, short press in to choose the menu, after adjusting, long-press in to save and exit Press left: switch vehicle speed and driving direction angle (move option after entering setting) Long press left: when you hear Didi turn off the buzzer, again turn on the buzzer Press right: switch time, satellite number, travel distance, travel time, acceleration time per 100 kilometers (move option after entering the setting) Multifunctional SinoTrack Heads Up Display Speedometer for Car Satellite time Satellite automatic time service, no difference in every second, not affected by natural factors such as weather Vehicle Satellite Altimeter The altitude is collected by satellite and is not affected by natural factors such as weather. Very high positioning accuracy Travel Time Calculation Shows the time have been driving, providing important driving data during a car journey so you can make next move Mileage Measurement Calculate the distance from the point of departure to the point of destination, know your driving travel distance Package includes Product Troubleshooting 1. The screen without any display, and no power Check whether the USB cable is damaged, replace the USB cable for testing, and prohibit the use of voltage higher than 5V for the power supply 2. Without car speed After HUD power-on, the satellite icon flashes will start to find the satellite. Please drive the car to the road. It will work after it stops flashing 3. Time adjustment After the satellite icon is flashing and the satellite is found, long-press in to enter the setting, short press in to turn to 6, adjust and calibrate the local time 4. Inaccurate speed a. First, check whether the speed unit is correct or not, the speed unit includes KM/H and MPH, please refer to the setting to switch the unit. b. The car manufacturers usually make the dashboard speed 5-7% higher than the ECU. The international standard is based on satellite data. (if the dashboard shows 100, and the device shows the 105, change the default value to 102) 5. Driving direction display error After the vehicle speed exceeds 5KM / H, the direction can be displayed normally. 6. Speed is still displayed after the car stops Under the underground parking lot, tunnel, and under the overpass, there will be unstable satellite drift when there is obstruction. 7. Turn off the buzzer Press left for 2 seconds to turn off the buzzer, again to turn it on.

Review: Exactly what I wanted, and then some! -- UPDATED! - (Additional updated information at the end of the review concerning customizing the display and the acceleration timer) When I discovered this device, I was just looking for something that would tell me how far I've driven on any particular trip, and then automatically reset to zero for the next trip. My car odometer can be programmed for that, but I usually keep it displayed to miles driven since my last refueling, so I wanted a separate display for the trip mileage. Not only can this device do that, but it does so much more! There are eight main functions: vehicle speed, compass heading in degrees, trip distance, trip time, time of day clock, elevation, acceleration timing, and number of GPS satellites that are being received. There is more flexibility in displaying this information than implied in the photos in the product's description! The left digital display can show either speed or compass heading, while the right display can show any of the other six functions (trip distance, trip time, etc.). The left and right displays are set independently, so there are a possible 12 combinations of what data is displayed. What's more, unlike what is implied in the photos, the display graphics and center compass gauge can be displayed with any combination of displayed data, not just with certain combinations. Also, it can be easily set to either English or metric units, and all settings are memorized, even when disconnected from power. There is also a speed alarm, but I have not tested it out yet. I also have not tested out the acceleration timer. If you find that the speed and distance readings do not match what your car's factory gauges read, then there is a way to calibrate that, as well. You may still have a slight error, but it's not much -- maybe about 1% or so. On a more specific point, I could have hardly asked for a better design for something like this for my car. I have a 2015 Honda Civic LX (9th generation Civic), and this device almost looks like it was designed for my car! Like the digital gauges on my dashboard, this device has white numbers with blue graphics -- albeit a different shade of blue. The overall shape of the display even mimics the shape of my car's instrument cluster! I believe the Si version of the 9th gen Civic has red graphics, so it would not be as good a match, aesthetically, but the functions would still work. There is supposed to be a way to turn off the graphics, but I have not found out how to do that, and I don't see it in the manual. It's no big deal for me, because I like the graphics, but some people might want to switch them off. Maybe someone here can weigh in on how this is done? Beyond that, this device is very easy to use -- just power it up through the USB port on the back of it. It gets all of its data through GPS satellite signals, so there is no need to hook anything to the OBD-2 port or anything else. All compass functions are also calculated based on GPS signals, so they are not affected by normal magnetic fields in the car -- but you do have to be moving for it to calculate a direction. It won't just tell you which way you're facing in a stationary vehicle when you power it up. And on my unit, I find it quickly locks on to enough satellites to work. However, the first time you use it, it may take a few minutes to locate the satellites, and in my experience, this is normal for most GPS-based devices. I'm using a USB power adapter that plugs into the cigarette lighter/power point. However, keep in mind that if you use a cigarette lighter adapter, some cars supply constant power to the cigarette lighter/power point, even when the car is switched off, so that this device would stay powered up when the car is off, unless you unplug it. It is designed to turn on and off based on whether it is getting power to its USB port, so there is no on/off switch on the device. Some people have reported that their unit broke down quickly. I have only been using mine for a few days, so I cannot yet comment on that. As long as it remains reliable, I feel this is a solid 5-star product! NEW INFORMATION -- Okay, here's the additional information that I have learned about this device. First of all, I figured out how to turn the decorative graphics on and off, and like so much else with this product, there are actually more options than expected. First of all, selecting these options is so easy that I'm almost embarrassed that I didn't figure this out before. All you have to do is just tap in the 3-way switch on the top of the unit. Remember, this switch can toggle left, toggle right, or push in. If you push it in and hold it, you enter the set-up mode. But if you simply push/tap it in briefly (from the regular usage mode, not the set-up mode), you step through various display configurations with each tap of the button. You can select from numerous combinations of having the outer-edge decorative graphics on or off, having the center graphic compass on or off, and even being able to turn on or off the left or right side digital displays, in case you only need to see one element of data and don't want a cluttered display. Very easy, and very versatile. The second thing I want to review is the acceleration timer, which I have now tested. It more or less works as you'd expect -- if you select this function when you're at a stop, it shows zero seconds, and then when you start moving, it starts timing. The only thing a little bit disappointing here is that, even if you have it set to display English units (mph, instead of km/h), it still times to a speed of 100 km/h, and not 60 mph, before it stops the clock and gives you a 0-to-100 km/h reading. I could determine this because, when in English units, it stops timing at 62 mph, not 60, and 100 km/h is roughly 62 mph. Keep in mind that this function will be approximate, anyway, because if it is GPS based, then there may be an error based on how often the unit reads the GPS satellites. For example, let's say that it reads the satellites 2 times a second (and that is just a guess). It knows that you're not moving when it takes two or more readings in a row that show you at the same position. But now, once you start moving, when it takes the next reading, it will see that you have moved and start the timer. However, if it is taking a reading every half a second, then it has no way of knowing exactly when you hit the gas during the half second between the time it saw you standing still and the time that it now sees you at a new position, so there could be an error of up to half a second -- again, assuming that it takes readings every half second. Even if it takes readings more frequently, there could still be a small error. The only way around this would be if it has an accelerometer built in that could sense the car moving without having to take a GPS reading, but I have not read that this device is equipped with an accelerometer. To me, this is no big deal. Just think of the acceleration timer as a neat feature to get approximate acceleration times at a test track, and not as a serious performance timer. This in no way detracts from all of the other cool features of this device.
Review: Works good - So far its been working great its pretty accurate except it tends to jump around a little bit but its only like 1 mph

## Questions & Answers

**Q: Will it save your trip mileage, in case you want to accumulate a few days in a row? Some say yes, others say no. Whats is it???**
A: Hello friend, Thanks for your question. As most of the HUD GPS speedometers on the market show, our SinoTrack GPS speedometer can only show the current trip mileage. As it relies on the USB cable from the car's power supply to connect the device to work, it does not retain previous distance data when the car is switched off, nor does it accumulate the total trip mileage with the power off. Please feel free to contact us with any questions. Thanks for your understanding and patience.

**Q: What is the "driving direction angle"? Does that represent a compass direction? Or maybe the incline of the vehicle?**
A: Hello friend,
Thanks for your question. Yes,  the driving direction angle is the compass direction, because the compass can only show the general direction, the display of DIR can show the angle of the specific driving direction, for example, 120° in the southeast, press the left button to switch the driving speed MPH and the driving direction angle DIR display. Any problem please feel free to contact SinoTrack customer service team.

**Q: Can this unit display kph as well as mph?**
A: Hello friend, thanks for the questions. Our SinoTrack GPS speedometer could display KMH or MPH. Just long press the button and then enter the "5" setting item, go left or right to select the unit you want, short press OK, and long press to exit the setting. Please kindly refer to the video. If you have any other questions, please feel free to contact us.

**Q: Wont this overheat during the Summer?**
A: This unit does not overheat during the summer.

### ⭐⭐⭐⭐⭐ Works good
*by R***S on February 2, 2026*

So far its been working great its pretty accurate except it tends to jump around a little bit but its only like 1 mph

### ⭐⭐⭐⭐ I am really grateful for this to be invented
*by J***X on May 3, 2025*

Really cool for the price, it worked by connecting it to by stereo on my car. I was a little skeptical but the reviews on here are legit & my experience with the speedometer was too. Recently got a car with the steering wheel on the right hand side, but the dashboard was in KM... I was left wondering hmm im going to learn how to convert on the go but I found this & put it inside the car. Love the idea of using this as a back up until I can remember the KM for MPH for roads of 15mph,25mph,35mph etc. The only bad thing I can say I have had it delay about 2 mins without it working. I knew it had to do something with the gps signal but it worked right after that. It never did it again prior to writing this review. I know it will go on again in the future, who knows how long these devices will last us. If you live in a hot climate area perhaps over time the screens will fade or dull out but im not 100% sure. It was plug and play for me & the build quality seemed good but not sure how long it will last with the sun hitting it constantly.
