KONNWEI KW206 Car OBD2 HUD Digital Meter Gauge All in One Automotive Trip Computer Smart OBD Speedometer Water Temperature Fuel Pressure Tester for All 2003 and Newer Cars

Funciona en santa Fe 2007

My wife drives a Chevy Sonic that has one of those terrible displays that shows very little live ECU data. A previous owner had chipped out the check engine and oil pressure lights from the dash, so an oil consumption issue (poorly engineered engine) caused it to run down to a half quart of oil and fry the piston rings. I tore apart the dash and discovered the chipped out diodes, and replaced the dash. It still didn't have much info. I replaced the engine (my wife loves the car) and apparently didn't connect a coolant hose to the heater core correctly. It was probably driven 150 miles until the hose popped off and sprayed coolant all over the engine. Thankfully, I pulled up to a stoplight and saw the steam. I probably wouldn't have noticed it if I was driving and it was blowing under the car. I would have had no idea that the engine was heating up until the check engine light popped on, because it didn't have a temperature gauge. This device not only gives a live display of the coolant temp (and multiple other data feeds), but you can set an alarm to go off if a data stream exceeds a set value. It should not be a needed device, as the car manufacture should make a dash that displays this useful data, but this little thing works quite well. The alarm gives me peace of mind that my wife should catch issues before they become drastic, and the live data readout is nice for when I am working on or diagnosing problems. It saves me having to bring my code reader from my other vehicle. All-in-all, this device is a great value.2 YEAR UPDATEThis thing still works great. It is able to read OBD II codes, but won't clear them. I've only tried it on one car, so it may be related to the make/model. If I need to, I just use my code reader to clear a code. For live data display, it works great. It turns on and off with the car and provides a good display for helpful data.

7/21/21So, I had bought this since my car (a 2008 Toyota Prius, don't hate me), lacks certain instrument readouts that some other vehicles do, or just don't show up on the main instrument cluster, ie: RPM or engine temperature. So, I had bought this product partly for those reasons, and, it has so far satisfied me. I haven't been able to really test the item extensively due to me getting it just a few hours ago, or today, when I type this, but, I am pretty sure that I'll update this review as time goes by. I definitely enjoy seeing what my engine RPM is, and this item I do feel like will get the job done, the question(s) is (are) will it be a reliable product and how long will it last for me.7/26/21So, having this just short of about a full week, I found that it'll be quick to reboot sometimes, that was for a few days, I was looking through my screen shots and noticed I took one of someone asking if there was a way to have it shut off for a start/stop vehicle when they shut their car down due to them being worried about it draining the battery down and someone mentioned about going into the settings and setting the start voltage to 13.5 volts, so I did. That does seem to have largely midegated the problem, but, it still reboots once in a while, it will do it when I go to turn my car on, I'm not sure if it is because of voltage fluctuations when turning on or what, but, hey. A few days after I got it, I hooked it up to my grandfather's friend's vehicle that does have a rpm guage, it seems to be like the kennwei rpm guage is about 500 or so rpm slower. While my grandfather's friend's vehicle was reporting about 1,200 rpm, the kennwei was reporting about 700 to 800 rpm, I'm not sure if that was just because of the vehicle reporting wrong or the kennwei was reporting wrong, I haven't tested which it is yet.8/27/21So, I was contacted by konnwei on my Amazon account message board, and pretty sure they mentioned about bringing the start voltage up to 14.5 volts to try to stop the device from rebooting (I think), it had the opposite effect, even sometimes shutting down while I was driving down the road. So, I think I dropped the voltage down to 13.8 volts, and eventually down to 13 volts, and seems to have mitigated the issue, but still does reboot. I noticed that, say I went 10 miles, that the device would be off about 1/2 a mile or more of total mileage traveled. I had mentioned to konnwei about the brightness and the reflection in the windshield in times of when the day transitions into nighttime, asking them if they could put out a update and/or if they had a type of hood that could mitigate or fix that issue, and, they mentioned that they had passed the feedback to their team.5/7/22I bought another one of these after I didn't have one for a while, and I received it yesterday (as of this part of the review), and, the one I have now seems to be a bit better as of right now in terms of not rebooting as frequently.

Worked fine for about a month (exactly one month to the day). Then, get in the truck today, crank the engine like normal, and instead of coming on the way it normally does, the Konnwei screen flashes and it makes an audible beep. Buttons still work and screen is on, but it will no longer connect to the ECU. I test my OBD port with another scan tool and it is fine. Konnwei has just decided it doesn't want to OBD anymore. I thought maybe if I updated the firmware there was a remote possibility I could trick it into behaving. I went to the official website to download the update tool. Invalid RAR file. How embarrassing. I've yet to see how their customer service is, but I'm not expecting much.Update: Customer service is even worse than the device. I had to send 2 emails over 2 days to their customer service before they even initially responded. Then, days would pass between volleys with me having to send reminder emails to spur them to respond. The final communication was them asking for a video of what was happening. I sent this, but then they went silent forever.

It functions for what I need it for. I haven't tried to update the firmware. Others mentioned that it is difficult to do that. It comes right on when I start my truck. You need to fully start your vehicle, otherwise it spends a long time in scan mode and then shuts off. I mainly bought it because I am visiting Canada this summer and I needed an easy way to read my speed in km. The metric speedometer in my truck isn't even visible in daylight and I don't have digital read out for speed. It does have a slight delay in catching up to the correct speed but it seems to line up with my speed in miles when it settles. When on cruise control it fluctuates between 1-2 mph plus or minus. Overall I would recommend it.
