Review on 🚘 Enhanced Model Y Heads Up Display (HUD) with Smart Digital Meter, GPS, Mini Fit, and HD Screen for Topfit Tesla Dashboard Speedometer by Jon Ford

No instructions, but found a video on You Tube and easily installed it. The device turned on for a split second and then went off. Came back for another, did the same. Told the company rep he sent me a video to install a completely different product! Went back and forth for a few emails, sent him pics. He said it installed correctly but maybe I had a defective one. Replaced with a new one, same thing. He offered to send another one, but I got the impression none of it worked. I also tried Acecar's HUD, the packaging looks the same and that block didn't work either. The seller sent me another block, the third, to test. And again the device didn't work for more than a split second. No improvement.
