BMW Homelink/Compress/Alarm Mirror Retrofit?

[Prost]

i see what the problem is. if you look at the homelink mirror there are nipples sticking out that interfere with the flange on the mount. now i remember that i had the same mount on my windshield but i had it replaced before i changed the mirror and the new windshield came with a smaller mount in diameter. you either need to get a smaller mount or just file down those nipples and you will be good to go.
What do you need pictures of? i don't have any more right now but i will put mine back on this week and i can take picture of whatever you want. or if you are around glendale one day we can meet up and i can show you.

Thanks, just think more pictures will help me more...I think I can go to a BMW dealer to get the mount for the new homelink mirror, that might be easier since the original mount is off now...thanks for all your details this last few days, I can go to Glendale anytime, it's not that far for me :D

Here is the old mirror:



New homelink mirror:



And the mirror mount from E30 windshield (fell off, need to put it back on):



Thanks, also, do you have more picture of your install?

Thanks, I will take some pictures tonight, so for a basic homelink function to work, just connect power (12V) on pin 3 and ground on pin 10 should work? Do I need to connect "other" wires?

I only connected those two on mine and homelink, compass and auto dimming worked As well. I searched around and saw that a pin out diagram mentioned another pin getting constant 12v but mine worked fine without it. Other pins have funcions like light sensor output for dimming side mirrors, reverse light input for disabling auto dimming during reversing, input for alarm indicator light...
For basic funcionality only power needed.

if you look inside the connector there is a tiny little 1 by pin1. I'll check tomorrow which one it is. I can't remember.

If your mirror still doesn't fit, take a picture of your mount and the mirror so i can compare it to mine. Maybe something is fishy.

Humm...I try and it doesn't fit on mine...let me try again, BTW, how do you know what pin number is on the mirror?

It does fit. They use the same mount. You need to put it on turned 45 degrees (maybe 60) and then turn it into position to lock it. Just be careful and don't break the metal piece off the windshield.

Well I had a getto solution first. I took apart a totally different connector that was used roughly the dame sized pins and just pushed them on the 2 pins. Later I got 2 female connectors from a junkyard. I still have the getto solution installed and you can kinda see it in the picture.

I see...BTW, how you mount the mirror on the windshield? The metal thing for the E30 stock mirror doesn't fit for the new homelink mirror...

Nice! Congrats!
On the mirror pin3 is +12V, pin10 is ground.
Here's where I got switched power from:

Ground is coming from the dome light ground
Switched power is from purple/grey wire from check panel
Hope this helps!

Thanks, but do you need some kind of plug on the mirror, I think I need a adaptor...

I am in SGV...

I just score a dimming and homelink one on eBay today for $50 (I guess I am doing OK :p)

Can you show me the wiring Picture?

[treff-7]

Thanks, yes, there are several version, all I need is homelink but I think any homelink one will have dimming by default (compress is optional). I really want to do it and do you mind to send me pictures? I also have an E30 Convertible...thanks a million ;)

I don't have it in the car currently.:-( I had the windshield replaced recently and it didn't come with the metal mount on it so I need to glue that on first. I can send you pics of the wiring though.
I guess you don't have a mirror yet. Here's an advice. These mirrors are expensive so to save some $$ I went on ebay and bought a mirror that have homelink, compass and all the bells and whistles BUT the mirror was broken so I got it for like $20. Then I searched again and bought another one that had nothing but dimming $25. I pulled the mirror out of that one and replaced the broken one. I had to cut the little window for the compass but it wasn't too hard and came out nice. The whole thing cost me $45 and I have a mirror that goes for over $200. You might be able to do something similar.

EDIT:
I just noticed you are in LA as well. Where exactly?

I have it in my car. i got power from the check panel so it turns off when you pull the key from ignition. dimming, compass and homelink are fully automatic, doesn't need anything but power. you can hook up the reverse signal and then it won't dim if you're backing up so you can see but it's not really needed. i personally love it! it appears to be hard to program the homelink sometimes but it might be just me.
Also i have a convertible so it goes right on the stock location on the windshield.

EDIT:
There are a few versions of that mirror. i believe there is one that has the homelink but no compass and maybe no dimming either but that i'm not sure of.
