Sometime in early 2008 Garmin will release the new Edge 705 HRM Outdoor Fitness GPS with Heart Rate Monitor
Of significant interest (to me) are these two items:
Full-Featured Navigation- No more scratch paper clipped to your handlebars or pulling maps out of your pocket. In addition to their cycling computer functions, The Edge 705 and 605 provide the same robust navigation as Garmin's vehicle navigators, with turn-by-turn spoken directions (turn left in 500 yards) and a 2.2-inch (diagonal) color display that shows maps in great detail. Both devices come pre-loaded with a built-in basemap, and a MicroSD card slot you can use to load new maps.
Connectivity and "ANT + Sport" - an approach to fitness devices as a total platform with the "ANT + Sport" connectivity system will interface wirelessly with any devices that are compatible with the "ANT + Sport" protocol, including devices from other manufacturers = power from third-party power meters.
