Sorry new questions below:

I am looking for info on upgrading my oem raidio (sucks...) tot he OEM with touchscreen and NAV. I bought the 2012 Premium used but it only has 3.5 inch display. From what I can tell the 2013 unit with 8in screen nav etc will bolt right in only changing the inner bezel. So my questions are surrounding re-programming the head unit to avoid security and other sensor errors... does anyone have a link to an earlier thread with details of this swap? Do I need to change the radio or are the nav features some kind of add on module like the screen? anyone have a price estimate on the reprogramming/ unlock if I change the unit?

I love my car just hate to always call OnStar for directions / I tossed my TomTom long ago! Not to mention I would like direct interface with Pandora etc ....
