Just thought I would share my latest install on my 2005 Civic, and give a shout-out to Bob’s Auotmotive Mirrors (who I am not affiliated with).
I purchased this auto dim mirror from him, with homelink and compass features. Bob provided everything and gave great support.
Wiring was really easy: Just remove the drivers side A-pillar, and connect the mirror to the fuse box (located above the accelerator pedal) using an add-a-fuse.
When it came to gluing the mirror base to the windshield, I opted to just take it to the local mobile glass company and had them do it.

Regards.
