If you're buying an A8 this year, prepare to spend a lot of time getting to know your new MMI system. We have consistently thought that Audi's buttons-and-knob interface is the best, and it looks like they've put an entire NASA team on the job of making it better. A seven-inch TFT screen with 800x400 resolution is now controlled by an 8-position joystick. Moving from one screen to another is done via "elegant crossfades," which sounds a bit PowerPoint-ish, but we'll wait until we see it to judge. And among other improvements, navigational maps can be rendered in "birds-eye perspective" 3D, with topographical map coloration. The only thing missing is the Encyclopedia Britanica. You can check out the exhaustive press release after the jump.

As previously reported, Suzuki has decided to include navigation on its SX4 Sport and Crossover before you make the first mark on the options list. That will make the $15,999 car the lowest priced car in America to come standard with talking maps. And now they're set to arrive in the SX4 Special Editions that arrive in Suzuki showrooms this month.

BMW's MY 2009 cars will get a new iDrive system with a 40GB hard drive. According to Bimmerfile, the drive allotment will have 12GB dedicated to navigational maps (and 8GB for entertainment and 10GB for your address book, because you've got more friends than music, apparently). With nav maps placed on the hard drive, BMW will no longer be providing a case full of map DVDs.

As of today, we're taking bets to see how long it will take before people realize that "GPS" does not stand for "Auto Pilot." The latest "But the GPS told me to..." story is brought to you by a charter bus driver in Seattle. Piloting a coach through the Washington Arboretum -- as the GPS instructed him -- the driver ignored, or didn't see, or didn't believe (take your pick) the flashing lights and sign warning him that his 11-foot-high bus was too tall for the looming 9-foot concrete overpass.
