I was thinking of upgrading mine as well. Did you buy it from Toyota? How hard was installation?

 

Well.. from the pictures. Looks like you just need to remove black plastic trim piece. Unscrew 1 screw to remove old rear view mirror. Place new rear view mirror and screw in 1 screw. Place trim back on. Done.

Anyone know if these are model and year specific? Can an older model toyota/lexus autodimming mirror work?

 

These frameless mirror has a standard window/windshield mounting piece(possibly made by gentex mirrors), you can use a different auto dimming mirror from gentex or other oem part it will fit, i test fitted it on my Subaru WRX-STi and it fits too. The reason i opted this specific part so i don't have to mess with wiring harness close to the toyota safety sense system on the windshield, only downside it does not have an auto dimming feature but i will surely upgrade this to a proper auto dimming/homelink mirror soon and already have provisions for power wiring from the moonroof switches.

Here is my other auto dimming mirror/homelink kit:

 

I assume this one is just battery powered then?

 

Yup. No wires. It includes a non-serviceable battery that likely lasts for a very long time, or warranty period. I don't know the exact time frame, but could look it up.

 

I've been looking at this since my wife was asking about whether or not our new Rav came with this. The link above is the best price I can find for it...even after shipping. However, Amazon shows this alternative. While it is far less expensive, the description mentions that you may need a spacer for compatibility. I'm not sure if my Rav will need that or not. If it does, then the spacer is another 50 bucks and the savings is pretty much gone. I'm more inclined to get OEM (especially if the cost is similar), but I'm interested in what the pros here have to say.

 

If you are worried about getting an alternative brand and extra parts to make it work, I recommend to buy the OEM Toyota Mirror.

 

I installed the OEM Mirror a few days ago on my wife's 2020 RAV4 XLE Premium. It was super easy to install. While pricey, it IS in fact a much much nicer mirror than the original not to mention the added functionality. I'd buy it again. Good Luck.

 

Can you tell us the part number for the OEM mirror? Auto-dimming as well as Homelink? And I'm puzzled, I thought XLE Premium would already have auto-dimming with Homelink.
I just bought XLE (with some added "convenience" package) and am annoyed to discover that I've got only the basic mirror.

 

Appreciate the input, guys.

 

I just had a Frameless Auto Dimming Rearview Mirror with Compass and Homelink installed in my RAV4 PRIME SE. Here is a picture of the part number. I chose this mirror because the Homelink is not battery powered like the other ones. It was wired in the overhead console area.

 

Wow, the part number shown in your photo gives me ZERO matches with Toyota parts and shows some garbage eBay hit with a WWW search.
But when I specify that I have a 2021 RAV4 to Toyota itself and then search for "frameless auto dimming rear view", I finally get some possibilities. Let's see, should I spend $900 or $2306? How on earth did you find this part?

 

This is straight from the Toyota dealership in Ontario, Canada. I believe it’s the exact same as the Gentex 50-GENK85A. The mirror that came in that Toyota box came with Gentex instructions on how to program the Homelink and Compass Zone. Funny thing, the dealer was selling it for cheaper than anywhere I can find on line.

 

I still can't confirm that the Gentex mirror can be installed on a 2021 RAV4 XLE without needing an adapter.
One Toyota dealer in Silicon Valley told me they could get the mirror for $216.32 - this is better than the Gentex replacement cost; they never asked for VIN. But my local Santa Cruz dealer first asked for my VIN (huh?), then told me that part is not available for my trim! When I told them about the other dealer, they claimed this dealer would probably be selling me a third-party, non-OEM part. They went on to tell me that I can't have the mirror I want because of wiring issue and furthermore it might require software configuration!
I'm starting to feel like I'm beating a dead horse.

 

I still can't confirm that the Gentex mirror can be installed on a 2021 RAV4 XLE without needing an adapter.

I bought and installed a GNTX-453 made for a Kia in my 2021 XLE. Definitely needed the mounting bracket extension to have the necessary clearance to adjust the mirror. All in I think it was like $35 for a brand new, never used, mirror with homelink/autodim via eBay and another $25 for the mounting bracket extension. The toyota mirror didn't appear to need an extension when I looked into all this initially.

I mean, it's 3 wires. 2 x 12v wires that can tap into just accessory or constant 12v + accessory 12v and then the ground wire. It wouldn't even interface with the rav's ECU or software. Were you looking at a mirror with the reverse camera running to it or something?

 

Installed OEM Accessory frameless rearview mirror with homelink buttons:

That smaller plastic piece that goes around the mirror stem - how do you remove it? I've been able to get the big piece (with small piece still attached) to slide off it's mounts, but it still encircles the mirror stem. It's crazy! How can it be so difficult?

 

Never mind, I got it. First slid the whole housing down, then I could get my fingers behind and push out the prongs that held the smaller piece.
But now I've got to figure out the wiring. It looks just like the one in the photo. Can I get power from any of those connectors?

 

I just installed the frameless homelink today. Pretty happy with it. Very easy.

 

I gave up on finding switched power in the vicinity of the mirror (moonroof didn't have it and was not willing to muck with the radar connector). A brief consideration of trying to run the wires to the fuse box led me to pay someone else to do it. Took it to Lott's Auto Stereo in Santa Cruz, paid for an hour of their time and got it done.

 

I installed Gentex Homelink autodim compass mirrors sourced from Amazon. I checked every single pin in the SE sunroof connector and found no 12 v switched wire. Instead I connected both the mirrors power wires to the 12 v switched radar camera wire for my 21 Prime last November and my wife's 22 Prime last May. Both work perfectly. I wanted the Homelink to work only when the car is on. I would have preferred it to work with ACC and ON, but got only ON.
I just dropped the entire perimeter of the headliner to change to Adventure rails and seal the rails better than the questionable factory arrangement. I found it would be absolutely no big deal to run a mirror power wire down to the fuse box if you don't want to connect to the radar camera. Find the Youtube video to install a Prinsu roof rack for details to loosen the headliner and remove the a-pillar cover.

 

For the wireless OEM Toyota homelink review mirror does anyone know how to replace the homelink battery once it goes dead?

 

For the frameless OEM Homelink Mirror there is no battery replacement. The packaging states it is a non-replaceable long term battery. ¯\(ツ)/¯

 

Wow a response after 2-1/2 years! 🤣. Well my battery is still working.

 

Yeah I just installed one today ... it took 5 minutes and I looked up how to replace the battery also and saw you can't
