I bought a Gentex 455 with compass to refit in my 1988 Town Car. The compass is built into the mirror and calibrated itself after 1 trip around the block.
There may be different color options for the compass, mine fortunately came in teal matching the rest of the dash lights, I got it on eBay for $25 removed from some Mazda, newer panther cars maybe the compass is green?
I took 12V in accessory from the same wire to my trunk popper button, but only because I didn't know at the time, under my driver footwell carpet there is the three wire plug for the factory auto dim mirror harness. It has 12V in run, ground, and 12v in reverse wires (Reverse sense force disables the dimming). If this connector is present in your car, it's the correct thing to pin into.
My 88's original mirror had a plastic button on the windshield incompatible with the new mirror, which thankfully came with its own metal button (. It had residual glue which I got off with a heatgun and screwdriver for scraping. I picked up a Permatex mirror button adhesive kit from Walmart (Auto part stores will have the same thing) and followed its instructions to adhere the metal button to my windshield. I never hooked up reverse sense.
