How do GPS applications for Nokia and Apple mobiles perform against dedicated in-car navigation systems?

If you have an iPhone, you don’t need to buy a dedicated in-car GPS unit. TomTom's unique car-phone cradle contains a built-in GPS receiver to boost the GPS receiver in the iPhone.

Apple doesn’t have the field to itself – Nokia has Ovi Maps for its GPS-capable phones. Our testing shows there’s a clear winner ... but one is free.
