Very excited with my new vehicle. 77000 miles, drives amazingly.

Couple of questions - How do I determine the MMI version I have? Found and downloaded version 4610, but unsure what I have currently? Also downloaded 2013 NAV maps, but want to be sure it is as easy as I read to install each of these? Is satellite radio free, because I currently have it and it works great? There is a attachment for an ipod, but what do I need to stream pandora through bluetooth?

It was in a minor accident, and the drivers side door is misaligned a bit. Can I fix that, and what do I need to do, or is that a job for a body shop?

Original battery, and has died on me once. Guessing I will need to replace it.

My keyless entry generally works great, but there have been a couple of times when it doesn't seem to work right. New keyfob battery?

What else should I know?

Coming from a 1999 Landcruiser, bit of a different driving feel :)
