"By the end of 2006, Garmin intends to have made all its popular hardware and software applications Mac OS X compatible. This includes the ability to load
MapSource map data to Garmin units via a
Mac, as well as waypoint and trip planning applications. Additionally, the Garmin nRoute application will allow Powerbook and iBook users to turn their laptop into a powerful street navigation tool with Garmin’s GPS 10 or GPS 18 sensors."
