Hi! I replaced the passenger side mirror recently and now trying to recalibrate the camera. I have read up on the appropriate steps, watched several videos, and have my six-dot target all ready to go. From all of the info I see to get to the right menu screen to start the aiming process, you need to press three buttons at once-- (audio) power, menu, and day/night button. Ok, I have tried doing this many times with no luck. Nothing changes. Does anyone have any other ideas? Thanks in advance for your help!
