There should be a page in the owner’s manual about no-mounting zones of the windshield if are any. For my ‘17 it is quite picky-sounding.

 

For my ‘17 it is quite picky-sounding.

I used the guide as more of a "suggestion" on my 2017. I found a lot of the exclusion area to be way out of the cameras' ranges. Once Subaru went to the cameras directly on the windshield, I suspect that the exclusion areas should have disappeared. (Although I could understand them showing exclusion areas that would interfere with the driver's vision.)

My dash cam is tucked behind the right side of the rearview mirror, so I can't even really see the screen (which shuts off anyway) when I'm driving. EZPass is up at the edge of the windshield on the passenger side where it would be blocked from my view if the visor was down. Both are in areas the Subaru tells me not to mount things, but they're also areas that the cameras can not actually see.

 

There were more windshield restrictions with the older eyesight system that was not attached to the windshield.

With your 25, as long as you don't block the cameras from the front, you're good to go.

 

The 2025 EyeSight cameras are in enclosures that extend right to the windshield. You can mount stuff on the inside of the windshield without worrying about obstructing the EyeSight cameras. Don't mount anything on the outside of the windshield in the areas that the EyeSight cameras look through. (Some dashcams have accessories that can be mounted to the outside of the windshield, like membranes that repel water. If you don't use these kinds of things, don't worry about it.)

 

Check your owner's manual under info for Eye Sight and front windshield. There is a very large area in the middle of the windshield that anything there could interfere with the Eye Sight System . Don't put anything there . I also have a 2025 Forester and read it when I got it last year.

 

On the 2025 the enclosures around the camera extend to the windshield. Compare that to the old EyeSight system where the cameras were out in the open and you could stick stuff in front of the camera, and the camera could see reflections of stuff on your dashboard. There is no problem mounting stuff anywhere on the inside surface of a 2025 windshield. That part of the manual didn't get updated.

 

I have a dash cam mounted on the windshield of my 2019 Forester, just above the rear-view mirror. Seven years in, no problems.

 

I have had BlackVue 970X dashcams installed on my 2017 Outback, 2024 Forester, and 2025 Crosstrek - all underneath EyeSight and behind rearview. No problems - no issues.

 

I have a 2025 Premium and I am running a dash cam all the time. Mounted on passenger side as high as I can get it.
