Finally haven taken the GPS plunge, thank you Santa, I now plot my current location, so that my Magellan Maestro 4210 North America can acquire at least three different satellite signals. The more signals it grabs, the more accurate its positioning will be. The device allows you to see your current GPS signal reception, the number of signals, the direction from which they're being received, and your current longitude and latitude. You can touch a Point of View (POI) icon for nearby services on the interactive map and see the address and phone number (when available) and get an instant route. The SiRFstarIII™ GPS receiver and built-in high-sensitivity antenna provide quick position acquisition for reliable navigation. QuickSpell™ intelligently searches and checks spelling so you can enter your destination with just a few touches of the screen. SmartDetour™ prompts you to route around sudden slow freeway traffic. The SD/MMC card slot may be used to Backup or Restore your receiver’s address book and store Custom Point of Interests (POIs). Backup and Restore is available in the receiver’s User Options from the Main Menu.
