This will draw on satnav giant TomTom, making a huge amount of information available to offer redirections around obstructions and up-to-the-minute updates to your ETA.
With full Siri integration, you can ask things such as "How do I get to Rainbow's End?" and "Where's the nearest petrol station?" or get Yelp to book you a table at a cafe. You can even ask it, "Are we there yet?".
Beyond that, though, Apple is working with car manufacturers to integrate Siri on the iDevice using a button on the steering wheel. This will mean functions can be undertaken hands-free while you're on the move.
Apple calls this Eyes Free as against Hands Free. Pressing the steering-wheel button will activate Siri without even lighting the screen, for less distraction. From then you control Siri by voice anyway.
In the next 12 months, BMW, Honda, Land-Rover, General Motors, Audi, Mercedes and Toyota intend to bring out models with this feature.
This could be pretty useful, since Siri is getting much more international support: Canadian English and Canadian French tunings arrive with iOS 6, plus Spanish tuned for Mexico, Spain and the United States, Italian, French and German tuned for Switzerland, and additional languages Korean, Mandarin and Cantonese with specific location tunings for the two Chinese languages.
French, German and Japanese, plus English tuned to the US, England and Australia, already exist. But there's no New Zild, so you'll have to speak clearly.
There has been speculation that a smaller 7-inch iPad is in the works.
This is a pretty tenuous rumour and there was no mention at the conference, but it would actually make sense for a car, in which an iPad is a bit too cumbersome and an iPhone too small.
