Not sure if the article covers it (I read Ars Technica's, not Verge) but the Slate site shows that they do have support for tablets, bluetooth speaker mounts, 3-seat back row, etc.)

While speaker wiring might be nice... I sense that's less likely to be readily supported. Mounts + wireless + USB port for charging is probably the limit there.

Of course, used truck buyers tend to be happy to run some wiring for things like CB, radar, extra lighting, etc. Doesn't matter if the wiring is showing!
