Jungs unser Amerikanischefreund hat schon anklappbare Spiegel aber die sind Manuel und nicht elektrisch! Und er fragt nach der moeglichkeit die Elektrik nach zu ruesten.
As you probably know there are a few countries in Europe were people refuse to speak english and unfortunately your car comes from one of them. :( I am sorry that I didn't see your posting any sooner cause the misunderstanding of my fellow german forum users was/is big.
But as one of the guys here wrote, adding the elektric parts isn't the only thing you will need to do. The wireing harness will need to be modified/extended, the car software will need to be updated as well, and the big question is if you are going to be able to get that software in the US.
For example on my E65 the mirrors don't fold up at first, the car just locks itself frmo the remote. I keep pressing the close button longer the alarm goes on and then the mirrors fold up, but this is something that you can set in the software.
