We've been seriously considering trading for a new 350 convertible, but I've visited three dealers and have yet to get a straight answer about the navi in this car. There's nearly nothing online, so I am hoping someone here has a reliable source of info.
The 2010 has hard drive based nav, I think. Is it possible to operate by means other than voice commands while the vehicle is in motion? Does it still have the region-based maps of previous generations? Is there any user-accessible space on the hard drive, as there is in the BMW 3 series?
My wife much prefers the IS350 over the BMW 335Ci (which I really like), but after the unpleasant experience we've had with our RX350 nav, I'm having a difficult time convincing myself that the IS will be any better.
Thanks for any input.
