Hi, I have a '22 Equinox. It did not come equipped with turn signals in the side mirrors. It does have blind spot detection. Is there a way to add signals to these mirrors.? The dealer says no. I had someone tell me that as long as you have power mirrors, you should be able to switch the mirrors out with signal mirrors with no problem. Can someone help? I feel like I'm going to get rear-ended without! Thanks!
