Comments on portable GPS units
Paper maps, co-pilots and maybe even Mapquest are becoming a thing of the past. With the availability of portable GPS units, which use Real time Satellite tracking and Map Data from NAVTEQ or Tele Atlas, you can now have reliable turn by turn directions to where you want to go. Finding restaurants, shopping malls, gas stations, ATMs, etc. is now available at your fingertips. Most portable GPS units have as many as two million points of interest and maps preloaded. With their portability, they can even be used by walkers, hikers and so forth. Many units even offer the capability to listen to MP3s and view pictures. And many of the units have long-lasting batteries that allow you up to 8 hours use.
