cartesian Conversion

[migcooper]

Hi All

I have a question regarding Cartesian coordinates. Hi was given a set of this coordinates and my tom-tom does not have this facility, so my question is, how do I translate 644-973 into something my GPS can handle like degrees or minutes?

I did search the internet but no useful help there.

Thank you all for the help.

Best Regards
MigCooper
