The mirror came from a Cadillac. These mirrors are made by Gentex and they come in all sorts of vehicles. The one in my 97 wagon came from a Ford E350. Some come with temp/compass and even HomeLink... the one in my Sonata has all that stuff. This mirror has 3 leads, power, ground and reverse light sensing. If you wire it to sense the reverse lights, then the auto dim turns off when in reverse. My Audi had that, but the car is not in reverse long enough to need to turn off the auto dim, so I wired the reverse sense to ground and that turns off that feature. The mirror is a windshield mount so you just get the metal button for a GM application and glue it up. The original Honda mirror cover gets double sided tape and gets taped to the headliner. The compass is self contained. You don't have to do anything for that....I wired to an ignition switched source...that way they won't be left accidentally on and kill the battery.
