The Auto Navigation 500 includes Nokia’s largest screen yet for one of its GPS models at 4.3 inches while merging the device with Bluetooth for hands-free calling support. An integral FM transmitter beams audio through a vehicle’s sound system and provides a convenient boost to sound for the built-in audio and video media players. Navigation is made easier with contact information for nearby points of interest and Traffic Message Channel support that provides live overlays of road congestion and the option of avoiding slower roads. The Finnish device maker plans to ship the 500 in the fall for 300 Euros ($410) and intends to launch the GPS receiver first in Europe with a memory card  preloaded with local maps.
