I don't think I ever had directions on my instrument panel (unless I am using built-in navigation)
I am a heavy Waze user and, like others on this thread, I would really like to see my upcoming turns on the instrument panel.
That being said, I have no problem glancing at the tablet to see where I need to be... My eyes are always cycling between left mirror, right mirror, rearview mirror, tablet and, of course what's up ahed.
