FAQ for 2012 5.0i?

[GPSnV1]

The manual and videos posted by BMW are helpful - Owner's Manual Videos - BMW North America.

I had a short training session with the salesperson and have done limited searches here. But is there a new-to-me FAQ for those questions that are asked all the time?

I have most of what I want configured with little time to devote to this but I have misses especially when compared to the BMW videos.

For example, I have Twitter going but not the mobile office email. I have most of the nav underway but am disappointed the night mode is not automatic. My traditional style garage door opener will not pair with the car after 5 or so attempts. I am using both USB ports and am not sure if the iPhone 4 media cradle will add features that would be useful to me. Some of my contacts and some addresses do not show up in the X5.

Anyway is thee a web devoted to such info? BTW, I have sports and premium but not techology.
