you mean the outside mirrors on the doors? id ask the toyota parts guy or a service tech how to do it. i did my mdx the other day, some azzhole broke my passenger mirror. the part was $45 at the dealer, $150 to have them do the whole job. i did the job myself. i aked the acura parts guy at the counter how to r & r the mirror, he showed me on the one i just purchased, it just slides and snaps into place, press down on the adhisive points. it was easy to figure out once i unwrapped the new mirror.
removing the mirror was a little bit of a pita, because it was cracked, but the install was super easy and fast. the whole job took 1 beer, about 10 mins.

1 min to grab a beer.
6 min to remove cracked mirror and heater wire.
2 min to connect heater wire and affix new mirror.
1 min to wipe mirror clean and toss empty beer can in the recycle.
