Review on Enhanced Auto-Dimming Rearview Mirror with Compass, Temperature Display - Compatible with Ford, Toyota, Nissan, Hyundai, Chevrolet, GM, Honda by Steven Hanson

I installed this mirror on a 2019 Nissan Frontier pickup because it didn't have any of the features that this mirror had. I'll admit it took some time to get the 12V circuit and temp sensors/wiring up and running. I installed the external sensor behind the grille on the side of the radiator as I found during research that this is the best place to get accurate readings. This meant the sensor and wiring were routed under the dash through the firewall to the front of the truck. Then I had to find a good spot for the internal sensor where I could get an average of the entire cabin. To do this I had to build an extra wire as the original wire wasn't very long. After that the mirror was fitted and the wiring harness routed through the headliner and under the dash, all connections were made under the dash on the driver's side. The mirror and all functions work as they should, I am very satisfied. The main thing I wanted out of all this was the compass and outside temp, everything else (auto dimming mirror and inside temp) was a bonus for me. This device is similar to others I've seen for sale but for less money. The instructions were pretty easy to understand and follow. The seller quickly answered 3 or 4 questions for me before I made the purchase, which I really appreciated. I give it 5 stars even though it took some time to install but I probably saved myself about $100 by not paying anyone to install it. I'll update my review if there are any issues later, but for now it's a very good device.
