Anybody know if the mirrors with the turn signals are interchangeable with the ones that don't? By interchangeable I mean that the turn signals would work. I haven't looked into this and was curious if someone has. I wish the track models came with the turn signals in the mirrors.

On KAI they do not indicate if special installation is needed. You can email them and James from KAI definitely should have an answer for you.

Logically the wiring for harness for the mirrors should be there because it would be way easier for Hyundai to change out the mirrors based on what model they are making, it wouldn't make any sense to only wire the cars with turn signal mirrors.

I know on the azera without the center speaker the connector is still there regardless. We don't have a grand touring models here at my dealer to look at. Next one that I see I will look at and report back.
