Recently I bought a F01 Car HUD from UOBD2 for US$58.99, connected it to OBD port and installed head up display unit easily. I have owned the tool for 2 weeks, and now I do not have to watch the dashboard to check speed and oil consumption anymore. The car HUD kit will reflect these data on the windshield directly. Here are 6 steps to install the tool.
Abut function
The Car HUD Display unit can display speed, engine revolving speed, water temperature, battery voltage as well as instant fuel consumption (the most useful function and that is what I love most about the tool). Besides, it will also remind you to shift gear and slow down when it is necessary.
About power consumption
The tool is powered via OBD port and it will automatically shut down about 5 minutes after parking. So there is no need to worry about lack of battery power.
Disadvantage
The only disadvantage is that its cable is only about 1.2 meter long, and I can only put the HUD on the left side of the vehicle because my OBD port locates lower than average ones.
