Re the idle. I am with you. I have had 4 other 6 cylinder BMWs and they were/are smooth and responsive. I kick myself regularity for a) selling my 2011 335 and b) for not considering a 35i X5. I can feel vibration in my steering wheel and wondered for a while if I had an engine mount going out, but 30k miles later it appears to be normal for the v8.

Don't know what you can do re the I drive. Mine is pretty sticky as well. But to be honest, while the I drive was nicer in my 2011, the navigation still sucked...
