GPS Cyclometers
The Garmin Edge series is comprised of cyclometer-type GPS receivers. All of them have high-sensitivity chipsets for superior satellite reception in urban canyons and under canopy. While they are excellent cyclometers, they aren’€™t all that great as navigation devices (more on navigation options below). If you are primarily wanting to track your performance though, the Edge series is an excellent choice.
The newest models are the Garmin Edge 605 and Edge 705, which add color screens and mapping capability (maps purchased separately) to the features found on previous models. The 705 adds a heart rate monitor, barometric altimeter
and the ability to share data wirelessly with another Edge 705. The 705 is also compatible with an optional cadence sensor and power meter. For a detailed look at the new Edge models, be sure to check out my hands-on review of the Edge 605.

The first-generation Garmin Edge 205 and Garmin Edge 305 (pictured at left) have a monochrome display and lack the mapping capabilities of the 605 and 705. The 305 will give you more accurate data on elevation gain than the 205, thanks to its barometric altimeter.
The Edge 305 actually comes in three models;€” the 305CAD
GPS receivers with turn-by-turn routing
If you want something for navigating the roads you’€™re riding, you’€™ll probably want a GPS with turn-by-turn navigation. The ones we’€™ll look at below won’€™t give voice-prompted directions, but they will “chirp”€ when a turn is approaching and give notification on screen too.
The eTrex Legend HCx is a good, budget minded choice, but the button layout on a GPSMAP 60Cx is much easier to manage while in a handlebar mount. In order to do turn-by-turn routing though, you’ll need Garmin’€™s City Navigator
