I am very new to GPS world.I am thinking of buying Garmin Oregon 300 Portable GPS. What are the differences between world map in "Garmin MapSource WorldMap (CD-ROM)(retail)" and world map in "worldwide basemap preinstalled in Garmin Oregon300" ?
Email Reply from Garmin staff: They are not the same....the world map gives you a general basemap for cities around the world..... Thank you for contacting Garmin International. With Best Regards, Software Support Specialist
