Garmin Edge 510
The draw: The new standard for head units
The newest computer from Garmin starts with every important head unit feature, and adds a few special touches that could make all other computers obsolete. GPS, speed, data download, ANT+ compatibility (to display data from other sensors such as power) are the core features. The incredibly intuitive touchscreen interface, mapping and brilliant display are great additions and, for the worried spouse or race spectator, the 510 allows others to track your progress in real time using Garmin Connect software.
