I've got a new Etrex 30, have read these pages, and aukadia (thanks Francis!) and am very grateful for all the guidance - goodness knows how you manage without all this.
I've managed to upload and download tracks and am learning my way around things, even completing the Silk Run 100 yesterday with no problems following the pink line (and even used Proximity alarms for info controls!). However, the Garmin Basemap (currently have no other maps loaded) are about 300m out of place which does not cause a problem, but it can be distracting. Is this something I've done, something I've NOT done, or something I should expect?
