New BMW Owner - Unclear on iDrive Update

Hello all. I have searched and searched but cannot seem to find a couple simple answers. I am sure I do not know the correct terms but here I go:

I bought a 2011 328ix with the nav and BT. I would love to upgrade the iDrive to the latest software version but really unclear on what can actually be done. My biggest goal would be to get internet access on my nav screen. Where I live there is massive bridge construction happening and I am constantly looking at my Android phone for updates on Google traffic. If I could get it to display on my nav screen, that we be so much easier/better/safer.



Thanks in advance for any help.

Erik
