ok peeps so this is my first post hopefully would help you ....
i searched couldnt find a DIY with pics ....
1. Remove battery cables
2. take your OE mirror
you'll have to unscrew your mirror (using a t20 torx)
and then pull downward with both hands n your slide it rite out.....

this is wat you'll c
3.Pull weather-stripping down past top of A-pillar
pull rite out dont be afraid you wont rip it ....
4. Remove your driver side A pillar Trim

you would see a trim retainer you can try to rotate it 90* with your finger (if you have small finger) or you can use something else...
you can kinda stick your finger between the A pillar trim and headliner
5. Remove coin tray
pull it towards you ..
6. Remove center dash panel
pull it towards you... gently because it has 10-pin a connector attach
make sure you remove the 10-pin connector
7. Now install your new Auto-Dimming mirror
just slide in where you took your old mirror off... really easy make sure you also tighten the screw
8. Route the wiring...
ok first connect your harness to the mirror and route wire between the headliner and roof, to top of the A pillar ....
(for those who dont wanna run wires on the A pillar because the air bag.. guess wat? camry already has wire on da A pillar... so no a problem at all )
also make sure you use some tie wraps.... 2 or 3 should be enough....
9. Cut about 1 inch of the plastic tubing on 10-pin connector wire bundle....
also identify your harness...
then attach a T-Tap the blue (ACC pin#8), white/black-stripped wire (GROUND pin#7)

.....make sure all wires are completely connect
Reconect your battery check if everything works and put everything back in place...
PD. you would get a "C" means calibrate once your drive around a 360deg around at 5mph or more the mirror would calibrate itselft
any questions let me know ill help ... this is a good upgrade for ppl trying to get homelink, dont be blind by ppl driving with HID, etc..
