gilly,

good, i think that we are on the same wavelength.

when i attempt to program this new mirror, according to the instructions in my owner's manual, an amber light blinks. and based on that manual, concluding, it blinks like crazy. this indicates that it has taken the code from my remote controller.

however, it fails to operate my garage door.

on the other hand, the overhead door remote that failed to program the mirror, continues to operate the garage door.

just for the record, when i first encountered this situation after acquiring this c140, i telephoned m-b care. i was told that the problem was with my mirror, that it antedated rolling code.

when i asked if replacing the o.e. 10.96 mirror would enable actuation of the garage door, i was disconnected.

clearly, there is something about this issue that causes m-b to run away from the question.

what is it do you suppose?
