Basically, it's quieter, may ride a bit different (I don't think I noticed it), slightly different colour scheme (the dark grey is actually dark) and some updates to the 5" MID (better graphics and new menus) and a new 6.1" MFD. You also gain LED DRLs.

The 6.1" Display Audio w/ Nav is ok. It's has some nice features and is reasonably quick (it's flash-based) but I don't know if people are too happy with it. You do get Entune too but you lose the JBL audio system from your 2010 (have to get a 2015 Four to get optional JBL GreenEdge audio). You will gain bluetooth stream audio and USB input and backup camera on the Three.

OH, and there's an attached Excel spreadsheet with 2010-2015 information. I found it too clunky and the post was too long for 6 years' worth of information so I entered it into Excel with tabs at the bottom for different years. That's why the main post only goes to 2013.
