When I purchased my car back in 2005, BMW Canada didn't offer the rear view mirror with integrated Homelink garage door opener. Now I have the opportunity to get one of those but wonder if that's a DIY job. I have the following concerns:
1. First, can I change the mirror by myself? How do I re-attach the mirror to the windshield?
2. I think the rain sensor is integrated in the mirror housing. So if I put a new mirror in (which of course also has the rain sensor) will it still work?
3. For the Homelink function, do I need to have the car program in order to get it to work or is it a plug and play?
4. Finally, if my stock mirror doesn't has the Homelink now, will there be a power supply for the new Homelink mirror?

Anyone has an answer? Rudy or Fred or Iceman?

The installation could be a DIY, depending on your abilities, I suppose.

Here's a document on how to remove and replace the mirror -- only you can decide if you're comfortable carrying out the procedure.

Also, I found some links to other threads on the subject. (One link contains an older version of the instructions posted above.)

Good luck!

Thanks Rudy! You are the best! :thumbsup:

So again, do I need to reprogram the car in order to have Homelink working?

No you dont need to reprogram the car for the homelink. If you need instructions for the homelink programming the homelink webpage has them. www.homelink.com
