Techadro TA-H1 HUD OBD2+GPS Smart Gauge Speedometer – High-Resolution, No Delay Head-Up Display, 10 Interfaces

This gadget met all my requirements perfectly! As a tech enthusiast, I wanted real-time access to battery voltage, mileage, RPM, time, temperature, and more, without installing multiple devices. The TA-H1 HUD does it all in one place, and I’m very satisfied with it.
The only drawback is that average mileage is displayed only in L/100 km and can’t be switched to km/l, even though instant mileage shows in km/l.

Works as described..but made in China! Thought it was Indian make. But nevertheless satisfied with what is offered and it does that..
