Interesting. I asked about that a couple weeks ago and they just told me "only the F150 models do that".
I see the "pro" model is available for the RAM, but the "pro" features dont come with it...weird.
Now I might wait even longer to see if they really do come out with the sequential signal version. Or maybe someone here will upgrade and sell me their original ones for cheap
EDIT: just saw your post with the screenshot. Website has been like that for weeks and is what made me contact them, because the Amazon "version" didnt mention sequential signals. They just told me only the F150 models get that....no mention of "in the works, check back soon".
