Wondering same thing myself. It looks like the parts for both mirrors to do so are around $650.00. Now the next question to answer would be is the wiring there for it, and can it be enabled in forscan. Oh and of course you've got to get a different dash bezel that has the camera button to toggle views (I think).
So just checked now camera wire on mine, not surprised. I did a little research as well on the activation and since I have the backup camera button the other camera views are activated from there on the dash so no need for those parts. Next question is what does your plug look like at the connection point from mirror loom inside of cab/door.
