Purchased my truck with the power towing mirrors that I didn't really want, so I swapped them with the full feature folding mirrors. I just plugged them in and all the functions worked perfectly. One very minor problem is the Curb View Assist. It is supposed to be an option in the DIC but it isn't there. Is it a program thing that my dealer can correct or is it just not going to be available to me because of the towing mirrors? Its not really a big deal, but i have noticed it to be a handy feature in the past.
