Navmii has released NavFree , which is free satellite navigation software for your iPhone or iPad. The application is available to download free from iTunes right now and is a fully functioning piece of software.

The functions of Navfree include the ability to search for addresses by postcode, street-name, house number and will be guided with full voice directions. The software will automatically re-route if you take a wrong turn and will also provide you with an estimated time of arrival, mark out points of internet and enable you to do a live search for local facilities.

You can buy additional features including the addition of speed cameras to your maps, petrol prices and traffic information.
