I've got the GG.Offroad cable system coming. Here's their Tundra video. They don't have a Tacoma video yet, but a guy on the other forum did it to his Taco.

I think it would take a change of the HVAC controls, since the volume knob is between the air vents. I also think they may be scarce since I tried to find a dealer with an OR Upgrade package + the 14" screen and it's not happening.
I won't sit in my new Taco for another six weeks or so. In the meantime, I'm shopping around for a topper. Leer told me they wouldn't have their's ready until late July or August. (Leer/Century are the same company.) A.R.E's are out.
I'll cut the order as soon as I have the final VIN.
