I suspected as much. It's very slow to react when you want to skip a song on iPod, it takes ages to offer the next screen after you've typed in a letter in the destination field, etc.Speaking strictly to the Jaguar brand he said the MY2009-11 XF SW interface is far superior to the (modified) XJ version they're trying to“cram” in the 2012 XF
The 2012 system feels like it's running a software that's too complex for it. I was thinking of downgrading to the earlier version, but your post suggests that's not possible.
So, the 2012 model has an inferior interface, and an inferior speaker system. Bummer.
