I just orded a Garmin GPSMap60cx. I should get it this early in the week, I can't wait!! The question I have is do I need to buy map software now or can I wait. I bought it for geocaching mostly but I'm sure I'll use it all the time. I'm also sure I'll be in the forums to search or ask questions. I'm looking forward to finding my first cache. Thanks for your answers in advance. Wizard750201
