I was using my etrex today (the yellow hand held one) when the battery ran out. I got home, changed the batteries and it wouldnt switch back on. I have tried about 10 batteries now including a pair of brand new ones, this doesnt help. Does any one have any ideas on what i could do to fix this or has it happened to anyone else? I planted a new cache yesterday and now i dont have the coordinates to post and i cant revisit because its over 150 miles away! any replies would be most greatly recieved, cheers, Dan.
