I have a 2014 Crosstrek that is about to finish its lease. I have signed for a new 2018 Crosstrek Limited with Technology Package. This will be my first Subaru with the EyeSight system. I have a highway transponder and was wondering if I can still mount it behind my rear-view mirror without affecting the EyeSight system. Same goes for a dash-cam that I want to mount there as well. Any comments from EyeSight users?
