2008 vs 2010 iDrive

[osunick]

Hi all,

From doing searches, I know the 2010 iDrive is a much nicer unit with higher resolution and 3D nav. I'm looking at E61 wagons and there's a 10K difference between 2010's and 2008's. Just wondering if there's any significant difference in functionality besides the user interface and nav. For instance, does the 2010 offer custom settings that aren't on the 2008? I'm also aware that the controller is much nicer from 2009-.

The 2008 535xiT's look like a nice deal, so I'd like to know what the extra money would go toward if I got a 2010. Thanks!
