I've only had it for a few days so far so I don't know how durable it is, but it seems to work good. It has a lot of different settings, so you can adjust a lot of things. It didn't really want to work at first in the 96, but you can manually make it hook up. And it works fine now. I also had to adjust the voltage 2 2 get it to shut off when I turn the car off but besides that, it works great, everything is really accurate and worked well i'm impressed so far. Review: Cheap but Impressive - This thing is awesome! I'm impressed with it so far. It works perfectly with a Crown Vic Interceptor. Some of the reviews I've seen where it malfunctions seem like they were made by people who tried to use this device in a car with an incompatible computer system. If you have an OBD II system at least up until 2011 (my car is a 2011), it should work The device is very accurate in terms of the speedometer and tach. The moment I hooked it up, I started getting readings I didn't know my car measured, such as air intake temperature, just to name one If you want the most out of your vehicle, I highly recommend this product. Just a heads up, initial hook will take a few minutes for the device to scan and determine what kind of sytem you have. And, at least for me, to enable sleep mode, I have to keep the key in the ignition until after the countdown finishes. Then the device will reboot with the logo. After that I can take the key out and it will do another countdown until going into sleep mode. Other cars or trucks may cause it to operate differently in this regard. Oh, and not to mention as a bonus, this device and scan for and clear out engine fault codes. The device also has very good build quality, and there's a slight weight to it, still lighter than a samsung galaxy phone, for example. EDIT: I've used the device for over a week now and it still works fine. It's accurate and timely. There's no lag in any of the readouts. For the sleep mode, I discovered you can just shut the car off and take the key out. It may do the countdown and reboot a few times, but it will eventually just go into sleep mode without you having to do anything else. Also, I did order an extra phone holder as the double-sided tape on the devices stand is not strong enough to hold up on a window for too long. This is a minor inconvenience compared to the overall quality of the product ## Features - ALL IN ONE OBD2 GAUGES ➤ KW206 Car OBD2 HUD display is the combination of automotive trip computer gauge and diagnostic scan gauge.

This is a minor inconvenience compared to the overall quality of the product ### ⭐⭐⭐⭐ Guage for some vehicles that lack some instruments *by M***N on July 21, 2021* 7/21/21 So, 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. 7/26/21 So, 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. 8/27/21 So, 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. 5/7/22 I 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. ## Frequently Bought Together - 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 - bbfly-A9 OBD II OBD2 16 Pin Splitter Extension 1x Male and 2X Female Extension Cable Adapter (2FT/60CM) - bbfly-B6 OBD2 Splitter 16 Pin OBD II Splitter Extension 1x Male and 2X Female Extension Cable Adapter (1FT/30CM) (1Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/243282733-konnwei-kw206-car-obd2-hud-digital-meter-gauge-all-in](https://www.desertcart.fi/products/243282733-konnwei-kw206-car-obd2-hud-digital-meter-gauge-all-in) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-08-28*
