While my '05 X is getting the driver's seat replaced, due to the seat heater burning a hole in the leather, I'm driving an '07 335i. The 335 has Nav, so I've been playing around with I-Drive.

Besides the interface being kind of clunky, I notice that it is very slow in executing a command from the controller. For example, switching from Nav to the Entertainment screen, takes a few seconds. Kind of reminds me of the response time of my old Windows 95 setup. Is this normal? I really was hoping to like I-Drive, since I'll have it in the X5 that replaces my '05 in a few months, but in the 335, it sure seems very, very slow.

I assume the X5 I-Drive setup is the same...any comments?
