I would like it to be able ;
Load other people's routes on to it and then follow them with clear directions GPX file ?
Display routes I have mapped
Display the loaded routes over OS maps 1:50 000 ? 1.2500 ?
Be able to use it for walking as well as bikiing along side a backup paper map
Have bike mount
Calculate distance travelled / milometer
In summary a reliable device I can use to explore new areas with clear on the ground mapping and directions, to avoid having to stop and consult the map at every junction possible crossing
Don't need HRM etc etc
Have used search on here but just throws up loads which I can't get a clear from on which would be best.
Thanks for any help
