Device turned off itself on waiting for a traffic light or slowing down. - I thought it’d be like my another HUD device that consistently showed up information on the windshield, but it wasn’t. My car is a 2025 Lexus hybrid, and I checked the online spec that it’s compatible. And it did show up all the speed information, etc. Unfortunately, this device only worked in a while after my car started. Then it turned off itself during a traffic light wait or even when I was still driving but maybe slowing down. This doesn’t make sense at all if my car was staying still or slowing down and it turned off itself. Then, I had to manually click the side button to wake it up. I don’t think that’s normal if that’s intended design. Or maybe I’m just in a bad luck to have a defective. Also, the light of the digits was so bright and didn’t dim in the night, which wasn’t supposed to be according to the product description. The light was bright enough under the sun, though. Anyway, I’m not going to try this again. Already wasted time reading the manual and installing that on my car. ## Features - 【APPLICABLE VEHICLES】——HUD A8 is only applicable to OBDII and EOBD, suitable for automobile of production years (OBDII and EOBD were used in other regions after 2003 and 2007 in other regions), but doesn’t support OBD I and JOBD. - 【LARGE HD DISPLAY】——A8 HUD is designed with an ultra-large HD 5.5-inch display, with clearer information display and multi-function switching, allowing you to monitor speed more comfortably, bringing you a better driving experience and more fun. - 【RICH DISPLAY DATA】——Almost everything you may need to read during driving will be displayed by this HUD, including vehicle speed, water temperature, voltage, driving distance measurement, voltage alarm, speeding alarm, free switching between kilometers and miles.

I don't understand what all the bad reviews are about, but this works 100% for me so far, if that changes in the future, I will come back and revisit this review however, for now, this is a perfectly visible, crystal clear image on my windshield and everything works as it should!
