GPS without data conection

[nursecosmo]

Hi all. I'm getting ready to travel to Guatemala this week and would like to use my recently unlocked GPS feture on my Omnia. Where I'm going I will not have a data conection, thus will not be able to use Google maps etc. So, what (free) program is out there which will allow me to have the maps loaded in my storage for use in the field? Please include detailed instructions on loading it if possible. Thanks a bunch in advance.
