2009 Homelink Mirror Retrofit - Cable required?

Hey guys,

I have a 2009 M3, build date 9/08. My car came with an autodimming rearview mirror without homelink or compass. I purchased an autodimming homelink mirror with ghosted compass off of an unknown vehicle.

Now that I received the mirror I have been reading DIYs in order to install and many mention a retrofit cable. If the connector in my car plugs into the connector in the mirror am I good to go? What is the retrofit cable for exactly?

Thanks,
