hmm... I would think the combination of the two would be the ultimate solution.... what I don't understand is why only the 3 series got the new I-drive controller for 09 and 5 and 3 series will get it for 10 with no software upgrades in the foreseeable future for the other series... at any rate, I still think that the Denso system in Lexus/Range rover is much more intuitive to use... and makes visual sense... most importantly the map is readable... for the life of me I can't make out street names on the little BMW screen
