obd2 water temp gauge

For OBD2 water temperature gauge, we recommend HUD display with OBD2 interface to display real-time data such as water temperature. Head up display means head up display. At first, it was mainly used in fighter and so on. When it is used on a car, you can keep looking straight ahead without looking at the dashboard when driving. Before, I always thought that it was not ideal to stick a piece of transparent paper on the front windshield to realize this function. I'm also worried about whether it will make the driving vision more tired. I haven't installed this thing all the time. Recently, I didn't pay attention to the water temperature, so I installed this to make up for the lack of water temperature display on the car dashboard. Although many BMW cars don't have this display, it's good to try installing one. It supports almost all models. Even if it is moved to other models, it can be used directly. It is a universal model.

Many riders have installed similar things, but they feel that the cost performance is not high. This thing is mainly to read OBD and display it without too much technical content. There are many navigation routes displayed on it, but the problem is that the navigation must use the map built in their app inside the mobile phone. Not like wechat positioning, you can choose third-party navigation apps in Gaode, Baidu and other mobile phones.

So I still buy this one, which has many functions, low price and good glass display effect. It also has built-in GPS, and there are many options for the interface. It's basically very good to use. There is no technical content in the installation: open the driver's door, remove a plastic plate on the side, and then remove the small tool box in front of the fuse box. Then push down the OBD interface clip of the original vehicle, retreat to the back, and connect the line to the OBD interface. Finally, thread the other end from the side to the lower end of the windshield and connect the machine. As for the length of the excess wire, tie it with a tie and fix it on the metal without making abnormal noise. If you think that OBD interface is not fixed well in front, you can tie it with a tie. There are many display interfaces to choose from. I took photos of each one, but I personally prefer the first one with more intuitive display. Left and right switching display function of wave wheel. RPM on the left and RTC on the right. The wave wheel can be switched left and right to become other functions. Since all data of this machine comes from OBD, only the speed is the speed of built-in GPS positioning, and there will be a gap between the default speed and the instrument panel.
