For those installing this to replace a standard mirror and they own a 2019 XLT base Explorer, read on.

First, the mirror looks good and I doubt most will be able to tell it's not stock.

Second, installation is easy, if you know the color codes on your wires of the map lights. I didnt. O.o I finally got it, but let's just say just because a wire has green on it, does not necessarily make it a ground.

Last, instructions.
1) Use a flat head screwdriver and insert at the base of the old mirror where it mates to the window. Pry out as you pull up on the mirror. If in doubt, google it. There are plenty of videos showing you how to do this.

2) Pull down on the sunglass/map light assembly gently. It will pull right out and unplug the wire from the lights. Set the assembly aside.

3) Get a machine screw with a head big enough to not pass thru the ground wire loop on the wiring for the new mirror. This will be your ground.

4) Get a drill and drill bit for drilling a hole for the ground screw. Use the minor diameter size for your drill bit for the screw size you are using.

5) Drill into the metal plate attached to the roof in the sunglass/map light cavity. Making sure it is NOT the roof of the car. Double check the distance between the plate and the roof. I had about two inches. Make sure your ground screw is not too long to inadvertently pierce the roof. That would be bad.

6) Install ground screw and wire.

7) Attach the red IDC clip to the yellow and green wire.

8) Push the clip of the other wire for the mirror into the back of the IDC clip.

9) Feed wires thru opening in cavity against windshield.

10) Zip tie excess neatly. Or cut and splice.

11) Plug wires into back of mirror.

12) Slide mirror into position on windshield and tighten the torx set screw.

13) Start car. Green light should be on in the front of the mirror.

14) Test by covering the sensor on the back of the mirror. It should dim.

15) Reinstall the sunglass/map light assembly. Make sure you plug the lights in.

You should be done

Good for the most part, would have been 5 stars if it came with a fuse tap, or even if the installation wire came attached with a fuse. Had to go to autozone to buy a fuse tap to hook up to my fusebox. My 2021 Rav4's internal fuse box actually turned out to have two spare fuses. After connecting the ground to a bolt installation was actually relatively seamless. Dims well at night, but sometimes the dimming is excessive.

The mirror is OEM quality, so it os very good. It functions to OEM quality as well. Installation is easy if able to connect to a 12V power source. I attached it with proper installation materials to the overhead lighting section which powers off about 10 minutes after locking the vehicle. So that worked pretty well. I did use the little cable channel to hide the wiring. What I don't like is that this mirror after a year of use is now a little loose around the ball joint. It would be difficult to find anything better than Genxtex however. The rattle does not create a noise and in most road conditions does not negatively affect its function. Most people might not even notice except when you move the mirror for adjustment.

I installed this rearview mirror using a fuse tap on my 05 Camry LE. I found a 10amp fuse that keys on in the fuse box inside the car and grounded to a bolt. It works great!

Once this mirror is installed properly it's great. It dims quickly when needed, but not so quickly that it's jarring, and the green power LED is dim enough to not distract you while driving, though it would be nice if you could turn off just the LED altogether.

However, I have two main complaints related to installation:

1) They don't include a wire cover. It's a tiny piece of plastic that goes a long way toward making the install look professional, but instead of including it they'd rather sell it separately for another $11.

2) The wires that come with it are just a bit too short to reach the stereo head unit, which would probably be the simplest place for most people to find a hot accessory wire to splice into. Instead I had to go probing factory harnesses in the passenger-side A-pillar for a suitable connection.
