For people who've upgraded their silver boxes and added the wiring.
I recently found out that GM 20870101 is identical to the older GM 25832462 except for color. 20870101 is white and 25832462 is charcoal.
I also found GM 13519224, also black, has the same plugs in the back as the other two receptacles but has TWO USB ports. It's spendy thought, almost $80 from Amazon.
Compared to about $22 or so for the others.
And I STILL haven't figured out where to mount mine!
