As most of you are aware, I was itching to replace my rearview mirror with a larger one AND use a HomeLink version to do so. I found a nice Gentex version on ebay for $50 and it even had red digits for the compass. I knew by simple examination that the mounting gimbal would need to be changed if it was even possible for the mirror to fit. I checked and re-checked the space, dimensions, clearances and found it all physically possible.
I split the replacement mirror carefully, wired up the device, programmed the HomeLink, changed compass zones and calibrated the compass. All was cool for the new one except to verify the gimbal mount exchange from the Audi mirror. I took out the Q3 mirror today, split it and found that the Audi mount is NOT even remotely practical to change over. The design is such that it's just not possible with out a new case and face design. The Audi mirrors made by Gentex are rather unique so this mod is going to be more of a challenge.
Plan B is to find a newer (13-14-15) used Audi mirror out of a Q5 or A5 that is the right size and has the latest 4 prong mount rather than the older (and NOT swappable either) 3-prong mount. This will fix my mirror issue.
See my HomeLink thread for thoughts and plans on that ...
