vwW12 - The F90BT only has about a 6" screen but the Z3 is 7". every inch helps. I kind of like the i-pod controls on the touch screen but then, I haven't seen either except online so...for me, the bigger the display the better. My biggest problem will be to find a good install shop close to my home base. Otherwise, it will be a trip to California!!I really like the 30 gig HDD, 10 gig for music, the rest provides the Nav functions, therefore; I can play a CD while using the Nav system. We'll see how it goes, still have to explain to the wife why I need $1800.00 of navigation and sound enhancements in a new car. ;)
I haven't been able tto find new map dvd's on e-bay for the Z-3, it's too new but I have found the equipment for $1195.95 - $1295.95, quite a difference from the $1795.00 I've seen at some sound shops.
