Is it possible to add a SMART camera and upgraded rearview mirror to a Premium? If so, does anyone happen to know the part #s? I did a few quick looks on the parts sites but wasn't exactly sure what the SMART camera entails. My hope is that the connections are somehow hidden and accessible easy enough somewhere in the rear gate. And for the rearview mirror, hopefully it'd be a relatively simple swap. I'm always trying to keep our rear cargo low as to not block the view, so I thought this may potentially solve the issue. Thanks!
