The iPhone has built in AGPS hardware which with the right software can be used to provide SatNav Functionality, there are several commercial SatNav applications available for the iPhone including the famous TomTom application but these tend to be expensive.
There are several free SatNav applications for the iPhones but most are dependant on having an active 3g connection to pull down the map data when you need it, this can prove to be expensive and if you haven’t got a data signal can be a problem.
One alternative application is called Navfree, which is free and stores the entire uk and Ireland road maps on the iPhone so no downloads are required during your journey. Navfree is easy to use and the navigation screens are easy to follow, and whilst it might be missing some of the extra functionality of commercial SatNav applications, eg live traffic updates, but if all you want is standard navigation then this is the perfect soltuion.
To install Navfree search for Navfree in the App Store.
