Hmm, good advice and I thank you, sir. My first choice was to get a mirror with the temp/compass and no autodimming, but I didn't see any that had the display without the autodimming--maybe if I poke around I could find one, or at least one where there's manual override for the dimmer. The wife won't be driving the car enough (I don't think, anyway) that the ergonomics are a big deal, but I also don't want to make it any more a PITA for her or me. How long did the compass/temp display last, btw? That's worth considering too, since I do have a GPS device that can render the compass unnecessary, and for a lot less cash I could just get a little inside/outside thermometer gadget instead. So maybe I'll hold off on the mirror and go for the USB/Bluetooth gizmo first, and of course the sexy lights. :)
