My car is a 2011 E90 328i with a 06/2010 production date.
I'm looking into retrofitting the rear view mirror with one that has homelink garage door opener, auto dimmer, and potentially compass. My current mirror has none of that.
After searching the forums, it seems that I need to use a retrofit harness: 61-12-0-434-330 but am not sure if this one will fit my car and if there are more than one flavor of these.
I checked on realoem and it looks like it will fit but it doesn't specify any years. Does it matter?
Besides harness, do I need to worry about anything else?
If anyone could help me out that would be great.
