I have a 2009 sport Trac. It has been dash compass and temperature readout. Probably about a year ago I was going to change the rear view mirror to one with a screen in it, but I never got around to doing it. Now I'm ready. There was a fix for the compass where you plug your original mirror harness into it and and it would keep the compass working without the original mirror. I can't seem to find it anymore. Anyone got a link?
