Well gents my brick but reliable and old friend of a Garmin GPS 12 finally climbed its last hill today and I need a replacement . I still always carry appropriate map and compass and to me the GPS sits on top of those to give extra info . So what basic functionality am I after Good battery life AA . Backlight for night use . Able to manually enter and name waypoints and create routes . and ability to invert routes . Navigate legs using a highway type of display . Ref to Ordnance Survey GB datum for Grid References . Walking speed and estimated time of arrival at next waypoint . Trackback I have only ever used this once when I dropped a map but using trackback found it . Total real distance covered during the course of walk / route . Is there any free software to enable me to create routes just by Grid Refs and legs on my Laptop and then transfer ? I am not interested in installing OS Maps onto any new GPS . I have looked at this Garmin eTrex Legend HCx Handheld GPS System Price Less than £150 Constructive comments / help please as to a suitable replacement .
