I assume you have tried it with the ignition switched on and the 'R' gear NOT engaged, right?
Coding is requiered if you have outer EC mirrors too or you want it disconnected when R gear is engaged.
Thanks for the quick reply. When I checked it last night it didn't appear to be working. I drove around my neighborhood to check the compass and it was working great. I covered my hand over the light sensor and it did not appear to dimm. When I drove to work this morning I had some jerk who was riding by rear. Fortunately the mirror started working; there was a big difference between the rear and the side mirrors.
To the guy who put this thread together, it's awesome, thanks!
