I have a Magellan Triton 400 and I can only enter coordinates by decimal point and I can not find how to change it to accept degree. I have found how to convert coordinates when using a computer or loading a cach with the Magellan software (vantage points) but it becomes a problem if we find coordinats in the field and do not have access to a computer. Can I make my GPS enter cords differently? Is there a formula I can use to convert cords on my own? Also, Triton 400 EATS batteries, any sugestions? Thanks for any help, slideways...
