Sure, I'll throw some up.

 

It depends on whether you are talking about the dimmer for the V1 concealed display or the auto-dimming capability of the mirror.

In the case of the V1 display that is incorrect, I have made dozens of these mirrors and it all depends how you do it. The etching in your mirror does not include the area where the light sensor is located, as such the display board will think it is dark all of the time and reduce the brightness. If this is not the case then the light sensor may have been removed and replaced with a resistor which would effectively set the brightness at a fixed level.

Now... if it's the auto dimming capability of the mirror we are taling about that is a different story. The current Porsche auto-dim mirrors cannot be etched, due to the way they are constructed the process will destroy the dimming gel. There are options, the manual dimming mirrors can be etched or either mirror can be rebuilt with two-way glass. If you really want auto-dimming and the embedded V1 display then there are options but mounting can be more invloved. If your Porsche mirror mounts on a "button" then it can be swapped for an Audi mirror with compass and embedded V1 display behind two-way glass.

There are lots of options, very mirror type is a little bit different and can require a different approach, believe me... I have cursed so many at times, I'd give my left nut if all manufacturers would use one type that was easy to modify!!
