Anyone using or used a Garmin Dakota 20 or Oregon series GPS on their trail bike? I've just seen this new Garmin GB Discoverer thing (basically OS 1:50k maps on the GPS, whilst retaining the vector data for turn by turn directions on the road) and it seems like it'll do exactly what I want on my trail bike i.e. on-road directions plus BOATs from the OS map.
Thoughts?
