RouteBuddy looks like a tempting program. However, I own a Garmin USB device. To use it on the road or track I need to upload maps to its memory chip(s) (North America, Europe, both topographical and street type). Since RouteBuddy is unable to do this (correct me if I'm wrong) I have no choice but to buy maps from Garmin (e.g. the Europe maps is about $300), install BootCamp and/or Parallels and/or Fusion, and buy and install Windows.
Having spent all this money on GPS and Windows products from Garmin, why should I buy RouteBuddy and all its individual maps in addition? I will end up spending about twice the amount again for the RouteBuddy software and all its maps that I am already forced to spend for Garmin software and maps.
Until RouteBuddy is able to download maps to the Garmin USB device this is simply too expensive, despite tempting features of RouteBuddy vs. klunky Windows GPS implementations.
