Feature: 1. 5.5‑inch color screen, reflective reading, lossless installation, plug and play, it won't take you too much time. 2. Practical driving data display functions, including driving speed, engine speed, instantaneous fuel consumption, average fuel consumption, local time, kilometers, acceleration time, voltage, water temperature, intake pressure, these can be detected and cleared. 3. When overspeeding, water temperature is too high, and voltage is too low, it will cause early warning of car failure. 4. It can effectively protect the battery in the car, while retaining the manual switch, which is more beneficial to control the HUD. 5. Wide application of range, universal type, and it is suitable for all the vehicles on the market.
