Garmin have released a new update for their Oregon x00 GPSrs - v3.70. But although it seems to have improved the clarity of their OSGB Discoverer maps, a few users have reported they can no longer see waypoints or geocaches on these maps (although they are visible when using the TOPO maps on the same GPSr!)

On the face of it I wouldn't recommend this update unless you don't mind this new bug - unless any intrepid users can tell me that they've updated their Oregon x00 to v3.70 without this problem showing up.
