Una, I noticed the 550 has been discontinued and the 550T seems to be a replacement. Was your unit glitchy? I like the more versatility to something like the Oregon or eTrex units. Plus the ruggedness of them is also appealing, since I am really hard on things.

It's compatible with heart rate and cadence sensors and excellent free or non-free maps are available. I can download routes from MapMyRide and ridewithgps and upload to those or Strava or Garmin Connect.
