Pocket-Lint: Why take two bottles into your car? Or something like that. That's kind of the thinking (albeit with less bottles) behind the Magellan Premium Car Kit for iPhone and iPod touch, which aims to do away with your satnav system and let you rely on your iDevice entirely for driving directions.
On Pocket-lint, we've covered apps like the Garmin StreetPilot before; apps that come at a premium (around the £50 mark) but are looking to replace your dedicated satnav. And whilst we've often been impressed with the details and data contained within the apps, the accuracy has always been a bit of a stumbling block. When it comes to driving, unlike walking, a quick response and absolute accuracy is required.
