Review on Extend Your Car Diagnostic Abilities with AUTOOL OBD2 16 Pin Male to Female Extension Cable for OBD 2 Head UP Display by Viswanath Badasz

The kit includes a tint square to stick on the windshield to prevent double vision but I didn't put mine on as double vision is almost invisible. Of course it's there, but it's so negligible during use that it doesn't bother me at all. I chose this model over others that have all sorts of other vehicle specs on the HUD and I'm glad I did. Nothing but speed, very minimalist. Recommend it to anyone who wants a simple HUD.
