One thing I have missed from my Elantra was the rear-view mirror with both compass and Homelink (and to a certain extent, the anti-glare abilities ). I like not having to have a garage door opener on my visors or the keychain fob that my current apt. building provides. So I decided to install a mirror. I located a mirror and harness from a 2009 Mitsubishi Galant (hoping that the mirror mounts would be compatible with my Mirage) for $45.
1. Remove the current mirror. All you have to do is pull the base towards the top of the windshield and the mirror slides off.
2. Install the mirror onto the mount. Slide the new mirror onto the mount and tighten the set-screw (Torx-15).
3. Wire in the new mirror. I'll show you where I attached the 3 wires from the mirror harness.
I attached the +constant and ground to the dome light, and reinstall dome light.
The +switched was a little different. I ran the wire along the headliner to the A-pillar and attached it behind there.
Remove the A-pillar moulding by prying at the top towards the center of the dash, and it'll pop off.
The brown wire on the harness is +switched and I attached the +switch from the mirror to it.
The wire all tied up.
Overall, a very quick and easy install.
