View Full Version : B7 rearview mirror into B5 - It works!

Hey guys,

I couldn't find much concrete information on this subject so I just decided to go ahead and do it myself. Like on most B5's, the autodim feature went to sh!t on my rearview mirror, so I took it as an opportunity to upgrade to one with a compass. I knew that B6 mirrors were direct replacements on our cars but couldn't find anywhere that said if the B7's could or not. I always liked this one more because it has the green dot and the compass is hidden into the glass, which I always thought looked a little better.

Anyways, it is basically a direct fit, and the only modification necessary is to cut about a centimeter off of the end of the plastic base cover so that it sits flush with our headliner. Everything else is straight forward and can be found at http://www.audiworld.com/tech/int36.shtml

Pretty sweet upgrade that can be had for cheap if you keep your eyes open!

Snapped a couple of pics along the way, although it was getting dark and hard to capture right. Note-in the second pic I had yet to put the plastic cover back on yet, but it fits fine if you cut a little bit off as I demonstrated in the first pic.

What benefit does the green dot have?

Also wondering if it'll work in a pre facelift. Willing to try just need to find a mirror.

My guess would be that it would work pre facelift as well, but I'm an 01.5 and have no clue what kind of changes were made throughout the years. The mount on the windshield should be the same, which is just a twist and lock system. Pretty simply stuff. Then as long as the 6 pin connecter is the same it will have power, which is all it needs. The compass feature/auto dim all come from within the mirror.

Anyways I'll try to clean it up and take a couple of better pics tomorrow to show it looks from elsewhere in the cabin.

So the current connector in your b5 a4 was plug and play with the connector in b7 mirror?

If you don't have a auto dim mirror already? Will this work?

I don't think it will work on some per facelift, at least plug and play. Like mine I have a 98 slick top base. Doesn't have auto dim, so I would assume there is no 6pin plug above my head liner.

^^^ We need more info on how to wire up this mirror to those who are pre-facelift, with no pre-existing harness.

Im interested in the whole wiring situation, i have a 2000 w/ what i am pretty sure was auto dim at some point in its life..(Mirror that has the lil hole in the bottom center) but now its a bubble. [headbang] I have couple yards near by that might have these mirrors. this would be a nice upgrade if it is possible for my car.

Yep it was. I don't think that 6 pin connector has changed yet.

For those who don't have autodim you would have to fab up some stuff to make it work. It might not be too much of a headache, but I'm guessing you would have to source one of those 6 pin connectors and then tap power from the sunroof. Something similar to how people hardwire radar detectors.

But you only need power to make this work right? Not any other signal cables?

^^^ That's what we should have been asking.

Yep just power. The compass and autodim features both come from within the mirror itself

I have a gray autodim for sale comes with the audi connector, snapring, and female end for mounting your stock mirror arm. Just pop the ball in. Doesnt have hidden compass but has red ambient lighting on the bottom that stays on. Oem and works perfect

I have this s4 mirror in my gti glx (twice the price as mine ha)

I have a gray autodimming with compass from the B7 up in the classifieds. It is the correct small mount used on the B5. Very hard to find since most B7's that had autodimming had the larger mount that was used in rain sensing cars.

Chances are it is the large mount. Its really obvious when you get it. The mount is huge. I made that mistake the first time i got it on ebay. Sent it back to the guy and he refunded my money

Yeah i can always do that i suppose; the add did not mention whether it was a small or a large mount. Did you have your gray mirror with a black or gray interior?

I'm intrigued by this. I have always wanted a compass in the car and auto dimming would be great as well. Well I guess I'm off to Ebay for a bit...

hmmm... yeah my rearview mirror in the past few months has started to have the "bleeding" in what ever it is that makes it autodim. This is good to know
