GTmedia V8 finder Pro 2 Localización

[Strike200]

Hi, I just purchased GTMedia v8 Finder Pro 2, and I'd like to know how to enter my location in latitude and longitude. My longitude has the minus sign (-1.27), and I can't enter the minus sign. Does anyone know if it's possible or what to do?

Enter the value first with no + - and then move to the east west and then it will allow change.
