Easy to use and looks great on the dash
This smart gauge is exactly what I needed. The 10 different display interfaces let you customize exactly what data you want on the screen, and the LCD is very clear during both day and night driving. 1 Setup was a breeze, and it accurately monitors everything from my speed to my fuel consumption. It's an awesome, inexpensive upgrade for any car. 5 stars! ... show more

obdII gauge display 2007 toyota prius
Review Image by mynor
★★★★★ Excellent addition for my 2007 Toyota Prius! I bought this for my 2007 Toyota Prius because the factory dashboard does not include a coolant temperature gauge. I wanted an easy way to monitor the engine temperature and make sure everything was operating normally. Installation was very simple. Just plug it into the OBD-II port and it starts working immediately. The display is bright, easy to read, and shows important information like coolant temperature, engine RPM, and battery voltage in real time. It has been working perfectly, and the temperature readings have been very consistent. This gives me much more confidence, especially on long drives and when climbing hills. If you own a second-generation Prius or any vehicle that doesn’t have a factory temperature gauge, I highly recommend this device. Great value and very easy to install ... show more

Not worth it
Review Image by James T
Yes, it's inexpensive, but doesn't work well. I was hoping to use this on a truck that didn't have enough value to warrant a more expensive guage package. When I plugged it into that truck, it just said it didn't have an OBD2 signal. A different scanner read codes just fine. Moved to a different truck, and followed instructions to see if there were any things I'm missing. It wouldn't display the RPM on the running engine. Just voltage, altitude, and an incorrect compass. Occasionally saying I was going 5MPH while standing still. Moved to a different car, same issues. So this one must be defective, however it still doesn't have much display options. It is also tiny. Photo against an IPad mini for reference, but the round portion of the display is about 2 inches. This thing is more bezel surround than anything. Yes, there are measurements on the ad, but the rest of the artificial photos are very misleading about how small this thing is. ... show more

Works great on 99 Honda Accord in OBDII mode
Review Image by SmartShopper
Wow, great collection of gauges and DTC scan tool itself is well worth the money. The DIGITAL dashboard showing the speedometer/rpm looks cool and modern. The HUD secondary gauge displays Coolant and Oil temp, Voltage, MPG, etc. The display is bright and comfortably clear in bright daylight under the California sun. Installation was simple, plug into the OBD port, then run the cable to the top of the steering wheel. The cable was extra long (about 6 feet) and I stuffed the slack into the fuse box above the OBD port. The included manual covers basic setup but honestly you can figure it out with only 3 buttons to work with. It took me 10 minutes to set the IMPERIAL units (MPH, MPG), set the time (UTC -8 hours), set the auto-turnoff volage to 13.2 volts, and the secondary gauges. For accurate MPG for my car, in the Fuel Settings, I set the Model to Honda and "Swept Volume" from 1.6 liters to 2.4 liters. My car is showing 28 MPG which seems correct. The latest firmware seems to have fixed the complaints found in user reviews. Among them that I found are listed below for those that are on the fence. 1. The "third display in the secondary gauges section" (which shows voltage) can be changed (yes all 3 can be changed now). 2. The display can be set to IMPERIAL (MPH, MPG, etc) or METRIC (KPH, liters/100 km, etc) in the Settings menu. 3. SPEED and RPM correctly matched the dashboard Analog gauges at freeway speeds for my 99 Honda Accord. 4. Clock time is accurate after adjusting the TIME OFFSET -8 hours in the Settings (time is auto-synched with GPS which is a plus). 5. No suction cup included in my package. I do not use it as it falls off unexpectedly during driving but incase you need it. 6. OBD cable is high quality and fits very firmly into the OBD port. Unplugging requires force and it will not unplug while driving on the road. 6. I wear polarized sunglass and can see the display crisp and clear in bright daylight. The display goes dark if you tilt your head 45 degrees. 7. Car parked for 2 days with HUD plugged in and the car starts up fine. HUD kept all my settings. Manufacturer does recommend unplugging the HUD if car is parked for 7 days. 8. For accurate MPG for your car, go into the Fuel Settings, set the Model (ie Honda) and "swept volume" from 1.6 liters to your engine size. ... show more

Provides very useful information on car performance
This is a great device and I like it a lot. I would have given it 5 starts except for a couple of issues that I think may be the reason why this is shown as "frequently returned". I think most users did not fiddle with it enough to make it work really well. I admit, my interest was perhaps a bit different from others so I was motivated to make it work. Here are the issues: 1. The "users manual" is almost useless. It is written by a non-native English speaker and is very cumbersome - if you can read it at all. It has very tiny text so you need a magnifying glass to read it. 2. The clock function is designed for international use so only shows 24-hour time values (14:30 = 2:30 PM) 3. Setting the clock is confusing unless you realize that it uses GPS time which does not know the loca time zone. You cannot set the time exactly. You can only set it within 30 minutes and then the GPS will figure out the time zone. 4. My car does not have a tachometer, compass or any engine instrumentation (it is a KIA pug-in hybrid) so I needed this to provide information from the OBD2 plug (it has a direct, wired plug-in - not bluetooth - which makes it much easier to use. Also, it does have the ability to show error codes and to clear the codes if needed so this is a plus. For things not in OBD2 (is has no magnetometer), it uses the GPS which is a great combination. It will also work in GPS mode only if you don't need the engine instrumentation. 5. The ad says it will not work with a plug-in hybrid (I didn't notice that) or on trucks, etc. It seems to work with anything with an OBD2 port - even pre 2009. I have a 2006 and 2008 Ford truck and it works great on both of those. 6. I love the shape and the suction cup mount. I put it in the very upper-left corner of the windshield where it is out of the field of view for driving but close enough to read even the small fonts. 6. However, it took a lot of fiddling to make it work with my KIA but it was worth the effort. The instructions for auto turn-on and turn-off (by time or voltage) still do not make sense to me but by continuing to tweak the values, I was able to make it work and now it does everything I wanted. ... show more

Nice little gadget.
Unit purchased for real time data for electrical system, and it works great. Has many functions, should work with most vehicles.

Functions fine (not as well in a Rav4 prime though), absolutely garbage manual
Review Image by Ovaltine Jenkins
Review Image by Ovaltine Jenkins
Bought this to get a tachometer functionality because some people on a forum recommended this to get a tach for a Rav4 prime. The issue with the Rav4 prime (and not so much with this HUD) is the battery voltage is super inconsistent. Sometimes it's over 14V, sometimes its at 12.8, 12.9V, and it can interfere w/ the voltage off, so unless if you're okay at working out some inconsistencies with this display, maybe don't get one for the Rav4 prime (I mean, the product description says it's not compatible w/ hybrids). The mounting tape wasn't very strong, and the suction cup was initially not "suction" at all until I took the proper time to get it suctioned on the window, and it has held itself in place ever since. There's an included screwdriver to remove the bottom plastic plate that you adhere the double sided tape to, I opted to removing that after getting the suction cup working properly, and used a piece of tape so the little remaining plastic bits have a soft place to sit on and doesn't damage the dash. 3 control buttons lets you to cycle between different display modes/entering into the settings/switching different readings on subsections of the HUD, and you're able to see readings like coolant temp, oil temp, transmission temp, turbo boost (if your car has a turbo), there's not too much customization, but there is a blanket reading page that just shows everything possible, if you need something like that. What is absolutely awful and not an excuse however, is the manual. There's like...no instructions on setting the manual, and it feels like half of the settings don't even do anything. There's also no way to disable certain warnings, like "high coolant temp warning", the only thing you can do is set it to an ungodly 200C. It also seems to shut itself off after the specified voltage after 3min regardless of what you set for the timer to turn this OBD2 off, at least that's what I assume what that setting is supposed to do, but there's no manual to tell me that. Given the price, this would absolutely be 5 stars had the manual actually detailed what all the settings did. ... show more

Very nice addition for monitoring vehicle information.
This is a nifty little gadget. Various display mode allows me to pick the type and data I want to see. It fits snuggly on the corner of the dash board. I use it to display oil, water, CVT(*) temperature in real time. In the first try, the timed auto-off didn't work and it stayed on. It turns that I also need to set the auto-off voltage to >13V. Then it will turn off when the engine is off and after the set time. The logic is a bit odd but it worked. I bought one each for my 2018 Forester and 2020 BRZ. I do need to tweak the speed by 2~4% so the reading matches the digital speedometer on the BRZ and the Garmin navigation on the Forester. It reads "CVT" temperature on the Forester. But on the BRZ 6MT it also has a "CVT" temperature readout. I am assuming it is just the temperature of the transmission gear oil? I wonder if there's a way to rename it or somehow they just use CVT to represent all types of transmission. ... show more
