3-99 (in my printed manual) doesn't address the compass at all..and it shows a mirror where the button underneath pushes forward and back for daytime/nighttime..very different from the mirror I actually have..where the button pushes in close to flush or out (showing green), and says nothing about the compass.
I notice that it defaults to the green position whenever I restart the car for the auto-dimming (thank you, mifiremedic, for that explanation).
The compass needs to have a control to dim and/or turn off/on???
I went to the manual pages on your link, AWD freak, thanks for that. It is quite different than the printed manual that actually came with my Crosstrek. The answer to my questions are in the link you posted for me. Thank you. Fie on Subaru for not giving me the same manual.
Next question. Is it possible to change the Subaru default setting for auto-dimming rear view mirror with compass so that the bright red compass digital display stays off when the car is restarted? And can be turned on when desired (rarely).
I find I am pushing the button to turn off the distracting bright red digital compass display every time I start my vehicle..which can be dozens of times of day. This is going to add up over the lifetime of the vehicle to thousands of times one has to turn off the compass.
It's kind of weird that the RV mirror would auto dim to eliminate glare at night, but also stick a bright red digital display on that mirror that is extremely distracting to viewing out the rear view mirror.
I believe the red compass default will always be on during startup, no matter what.
A solution to reduce the brightness of the compass display would be to stick on a dark-tinted film directly on it. Otherwise, another solution would be to replace the rearview mirror entirely with the model with only the auto-dimming mirror function.
