Purchasing AAwireless Two

I am contemplating purchasing AAwireless for Andriod Auto, don't like my MA1 anymore. I will be using it with my wife as a second user.

  1. Should I get it? Pro / Cons?

  2. How easy is it to switch between users while driving?

  3. On long trips family wants watch movies (mp4s) and youtube from the phone? Possibile?

Thanks

Imran
