Garmin 820 GPS device (Chorley Moor PR7)

A Cycling GPS device. This is now been replaced by the 830. This is undoubtedly a good thing as this device never worked to my satisfaction. I suspect it was a dud product, but Garmin persevered with it. They replaced my first one with this one, but it still wasn't up to scratch. I wanted it purely for navigation, but it wasn't that good, and would sometimes freeze. I have since replaced it with a different make! The computer facilities, such as speed, distance, elevation etc all work, but I didn't want it for these. It was however an expensive purchase and ought to be functional. If anyone would like to be bothered using it, or maybe has experience with the same model and feels they can use it successfully it will save it being thrown away.
