Some time ago I got myself a Garmin Etrex because i thought it would help me find my way around but all it did was confuse me and I've never really used it in anger. Recently i was in a car with a Tom tom and it seemed so easy to use i thought i would revisit the Bike GPS thing, so it's advise I need ! What can I get to use on the bike that will run for a day, show ALL the roads and bridleways, and be simple to use ? I am reasonably sure I really don't need any particularly advanced features but maybe when I've mastered whatever I buy i might !! Who knows. Also my budget is limited so s/h would be OK, and I suppose if i buy a new GPS the Etrex which is almost unused will be for sale if they are worth anything. Any ideas ?
