I'm noticing a few different p/n's for units with auto-dimming, compass, and homelink;
0000-8C-H73
0000-8C-H73
0000-8C-R01A
0000-8C-Z08B
... and probably more if I keep looking. They look identical and I'm sure they all just need +12v and ground to work, but I want to make sure I get one that keeps the cable going up to the headliner covered and fits the best. I also don't know if colors (buttons/button illumination, compass display) differ between them or not. If anyone who has installed this can show a picture of theirs and provide their p/n, I would be grateful.
